Runtime errors happen without warning. The error message can come up the screen anytime DAEMON Tools is run. In fact, the error message or some other dialogue box can come up again and again if not addressed early on.

There may be instances of files deletion or new files appearing. Though this symptom is largely due to virus infection, it can be attributed as a symptom for runtime error, as virus infection is one of the causes for runtime error. User may also experience a sudden drop in internet connection speed, yet again, this is not always the case.

(For illustrative purposes only)

Causes of Daemon Tools Engine Error Code 1784 — Code 1784

Step 3 – Ensure Junk Isn’t Causing Daemon Tools Engine Error Code 1784

Any space that isn’t regularly cleaned out tends to accumulate junk. Your personal computer is no exception. Constant web browsing, installation of applications, and even browser thumbnail caches slow down your device and in the absence of adequate memory, can also trigger a Daemon Tools Engine Error Code 1784 error.

So how do you get around this problem?

• You can either use the Disk Cleanup Tool that comes baked into your Windows operating system.
• Or you can use a more specialized hard drive clean up solution that does a thorough job and flushes the most stubborn temporary files from your system.

Both solutions may take several minutes to complete the processing of your system data if you haven’t conducted a clean up in a while.
The browser caches are almost a lost cause because they tend to fill up quite rapidly, thanks to our constantly connected and on the go lifestyle.
Here’s how you can run the Window’s Disk Cleanup Tool, without performance issues or surprises.

• For Windows XP and Windows 7, the program can be ran from “Start” and from the “Command Prompt”.
  • Click “Start”, go to All Programs > Accessories > System Tools, click Disk Cleanup. Next choose the type of files you wish to remove, click OK, followed by “Delete Files”.
  • Open up the Command Prompt, type “c:windowscleanmgr.exe /d” for XP and “cleanmgr” for Windows 7. Finish by pressing “Enter”.
• For Windows 8 and Windows 8.1, the Disk Cleanup Tool can be accessed directly from “Settings”. Click “Control Panel” and then “Administrative Tools”. You can select the drive that you want to run the clean up on. Select the files you want to get rid of and then click “OK” and “Delete Files”.
• For Windows 10, the process is simplified further. Type Disk Cleanup directly in the search bar and press “Enter”. Choose the drive and then the files that you wish to wipe. Click “OK”, followed by “Delete Files”.

The progressive ease with which the Cleanup Tool can be used points to the growing importance of regularly deleting temporary files and its place in preventing Daemon Tools Engine Error Code 1784.

PRO TIP:
Remember to run the Disk Cleanup as an administrator.

Step 4 – Fix Infections and Eliminate Malware in Your PC

How do you gauge if your system is infected with a malware and virus?

Well, for one, you may find certain applications misbehaving.

And you may also see the occurrence of Error 1784.

Infections and malware are the result of:

• Browsing the Internet using open or unencrypted public Wi-Fi connections
• Downloading applications from unknown and untrustworthy sources
• Intentional planting of viruses in your home and office networks

But thankfully, their impact can be contained.

• Enter “safe mode” by pressing the F8 key repeatedly when your device is restarting. Choose “Safe Mode with Networking” from the Advanced Boot Options menu.
• Back up all the data in your device to a secure location. This is preferably a storage unit that is not connected to your existing network.
• Leave program files as is. They are where the infection generally spreads from and may have been compromised.
• Run a thorough full-system scan or check of an on-demand scanner. If you already have an antivirus or anti-malware program installed, let it do the heavy lifting.
• Restart your computer once the process has run its course.
• Lastly, change all your passwords and update your drivers and operating system.

PRO TIP: Are you annoyed by the frequent updates to your antivirus program? Don’t be! These regular updates add new virus signatures to your software database for exponentially better protection.

Step 5 – Return to the Past to Eliminate Error 1784

The steps outlined up until this point in the tutorial should have fixed Daemon Tools Engine Error Code 1784 error. But the process of tracking what has caused an error is a series of educated guesses. So in case the situation persists, move to Step 5.

Windows devices give users the ability to travel back in time and restore system settings to an uncorrupted, error free state.
This can be done through the convenient “System Restore” program. The best part of the process is the fact that using System Restore doesn’t affect your personal data. There is no need to take backups of new songs and pictures in your hard drive.

• Open “Control Panel” and click on “System & Security”.
• Choose the option “System”.
• To the left of the modal, click on “System Protection”.
• The System Properties window should pop-up. You’ll be able to see the option “System Restore”. Click on it.
• Go with “Recommended restore” for the path of least hassles and surprises.
• Choose a system restore point (by date) that will guarantee taking your device back to the time when Error 1784 hasn’t been triggered yet.
• Tap “Next” and wrap up by clicking “Finish”.

If you’re using Windows 7 OS, you can reach “System Restore” by following the path Start > All Programs > Accessories > System Tools.

Step 6 — Error 1784 Caused by Outdated Drivers

Updating a driver is not as common as updating your operating system or an application used to run front-end interface tasks.

Drivers are software snippets in charge of the different hardware units that keep your device functional.

So when you detect an Daemon Tools Engine Error Code 1784 error, updating your drivers may be a good bet. But it is time consuming and shouldn’t be viewed as a quick fix.

Here’s the step-by-step process you can go through to update drivers for Windows 8, Windows 8.1 and Windows 10.

• Check the site of your hardware maker for the latest versions of all the drivers you need. Download and extract them. We strongly advice going with original drivers. In most cases, they are available for free on the vendor website. Installing an incompatible driver causes more problems than it can ever fix.
• Open “Device Manager” from the Control Panel.
• Go through the various hardware component groupings and choose the ones you would like to update.
• On Windows 10 and Windows 8, right-click on the icon of the hardware you would like to update and click “Update Driver”.
• On Windows 7 and Vista, you right-click the hardware icon, choose “Properties”, navigate to the Driver panel, and then click “Update Driver”.
• Next you can let your device automatically search for the most compatible drivers, or you can choose to update the drivers from the versions you have on your hard drive. If you have an installer disk, then the latter should be your preferred course of action. The former may often get the driver selection incorrect.
• You may need to navigate a host of warnings from the Windows OS as you finalize the driver update. These include “Windows can’t verify that the driver is compatible” and “Windows can’t verify the publisher of this driver”. If you know that you have the right one in line, click “Yes”.
• Restart the system and hopefully the Daemon Tools Engine Error Code 1784 error should have been fixed.

---

Step 7 – Call the Windows System File Checker into Action

By now the Daemon Tools Engine Error Code 1784 plaguing your device should have been fixed. But if you haven’t resolved the issue yet, you can explore the Windows File Checker option.

With the Windows File Checker, you can audit all the system files your device needs to operate, locate missing ones, and restore them.
Sound familiar? It is almost like “System Restore”, but not quite. The System Restore essentially takes you back in time to a supposedly perfect set up of system files. The File Checker is more exhaustive.

It identifies what is amiss and fills the gaps.

• First and foremost, open up an elevated command prompt.
• Next, if you are using Windows 8, 8.1 or 10, enter “DISM.exe /Online /Cleanup-image /Restorehealth” into the window and press Enter.
• The process of running the Deployment Image Servicing and Management (DISM) tool may take several minutes.
• Once it completes, type the following command into the prompt “sfc /scannow”.
• Your device will now go through all protected files and if it detects an anomaly, it will replace the compromised version with a cached version that resides at %WinDir%System32dllcache.

Step 8 – Is your RAM Corrupted? Find Out.

Is it possible? Can the memory sticks of your device trigger Error 1784?

It is unlikely – because the RAM chips have no moving parts and consume little power. But at this stage, if all else has failed, diagnosing your RAM may be a good move.

You can use the Windows Memory Diagnostics Tool to get the job done. Users who are on a Linux or Mac and are experiencing crashes can use memtest86.

• Open up your device and go straight to the “Control Panel”.
• Click on “Administrative Tools”.
• Choose “Windows Memory Diagnostic”.
• What this built-in option does is it burns an ISO image of your RAM and boots the computer from this image.
• The process takes a while to complete. Once it is done, the “Status” field at the bottom of the screen populates with the result of the diagnosis. If there are no issues with your RAM/memory, you’ll see “No problems have been detected”.

One drawback of the Windows Memory Diagnostic tool pertains to the number of passes it runs and the RAM segments it checks.

Memtest86 methodically goes over all the segments of your memory – irrespective of whether it is occupied or not.

But the Windows alternative only checks the occupied memory segments and may be ineffective in gauging the cause of the Daemon Tools Engine Error Code 1784 error.

---

Step 9 – Is your Hard Drive Corrupted? Find Out.

Your RAM or working memory isn’t the only culprit that may precipitate an Daemon Tools Engine Error Code 1784 error. The hard drive of your device also warrants close inspection.

The symptoms of hard drive error and corruption span:

• Frequent crashes and the Blue Screen of Death (BSoD).
• Performance issues like excessively slow responses.
• Errors like Error 1784.

Hard drives are definitely robust, but they don’t last forever.

There are three things that you can do to diagnose the health of your permanent memory.

• It is possible that your device may have a hard time reading your drive. This can be the cause of an Daemon Tools Engine Error Code 1784 error. You should eliminate this possibility by connecting your drive to another device and checking for the recurrence of the issue. If nothing happens, your drive health is okay.
• Collect S.M.A.R.T data by using the WMIC (Windows Management Instrumentation Command-line) in the command prompt. To do this, simply type “wmic” into the command prompt and press Enter. Next follow it up with “diskdrive get status”. The S.M.A.R.T status reading is a reliable indicator of the longevity of your drive.
• Fix what’s corrupt. Let’s assume you do find that all isn’t well with your hard drive. Before you invest in an expensive replacement, using Check Disk or chkdsk is worth a shot.
  • Open the command prompt. Make sure you are in Admin mode.
  • Type “chkdsk C: /F /X /R” and press “Enter”. “C” here is the drive letter and “R” recovers data, if possible, from the bad sectors.
  • Allow the system to restart if the prompt shows up.
  • And you should be done.

These steps can lead to the resolution you’re seeking. Otherwise the Daemon Tools Engine Error Code 1784 may appear again. If it does, move to Step 10.

Step 10 – Update Windows OS

Like the software applications you use to render specific tasks on your device, the Operating System also requires periodic updates.
Yes, we’ve all heard the troubling stories.

Devices often develop problems post unfinished updates that do not go through. But these OS updates include important security patches. Not having them applied to your system leaves it vulnerable to viruses and malware.

And may also trigger Error 1784.

So here’s how Windows 7, Windows 8, Windows 8.1 and Windows 10 users can check for the latest updates and push them through:

• Click the “Start” button on the lower left-hand corner of your device.
• Type “Updates” in the search bar. There should be a “Windows Update” or “Check for Updates” option, based on the OS version you’re using.
• Click it. The system will let you know if any updates are available.
• You have the convenience of choosing the components of the update you’d like to push through. Always prioritize the security updates.
• Click “OK” followed by “Install Updates”.

Step 11 – Refresh the OS to Eliminate Persistent Daemon Tools Engine Error Code 1784 Error

“Windows Refresh” is a lifesaver.

For those of you who are still with us and nothing has worked to eliminate the Error 1784, until recently, a fresh install of Windows would have been the only option.

Not anymore.

The Windows Refresh is similar to reinstalling your Windows OS, but without touching your personal data. That’s hours of backup time saved in a jiffy.

Through the Refresh, all your system files become good as new. The only minor annoyance is the fact that any custom apps you’ve installed are gone and the system applications you had uninstalled are back.

Still, it is the best bet as the final step of this process.

• Enter the “Settings” of your PC and click on “Change Settings”.
• Click “Update and recovery” and then choose “Recovery”.
• Select “Keep my files”. This removes apps and settings, but lets your personal files live on.
• You’ll get some warning messages about the apps that will be uninstalled. If you’ve gone through a recent OS upgrade, the Refresh process makes it so that you can’t go back to your previous OS version – if you should ever feel the need to do it.
• Click the “Refresh” button.

Are you using an older version of Windows that doesn’t come with the power to “Refresh”?

Maybe it is time to start from scratch.

• Enter your BIOS set-up.
• This is where you need to change your computer’s boot order. Make it so that the boot happens not from the existing system files, but from the CD/DVD Drive.
• Place the original Windows disk in the CD/DVD drive.
• Turn on or restart the device.
• Choose where you’d like the system files to be installed.
• Your PC will restart several times as the process runs its course.

FAQ’s

What are Runtime Errors?

A runtime error, also often known as a program error, occurs while the program is active and running. The result of the error may lead to a program crash. However, there are other types of similar program errors such as logic errors and memory leaks. More commonly known as bugs, such errors are usually identified during the debugging process.

Should I Restore My Computer to Fix Runtime Errors Like Error 1784?

Restoring your computer to an earlier version may solve the problem, depending on what’s causing the runtime error. For example, if it’s due to a hardware issue then restoring your computer to an earlier date may not solve the problem. However, if it’s because of a newly installed program, then restoring to a date before the corrupt program was installed may do the trick.

I’m Not A Computer Technician, Can I Still Fix Errors like Daemon Tools Engine Error Code 1784?

Yes, you can fix most issues related to runtime errors even if you are not a computer technician. These include errors like Error 1784 and Error 1784. Refer to a step-by-step guide and follow all the tips. You may also use a specialized software to get the job done. They are easy to use and require little to no work on your part. You can merely install the software and have it perform the job for you. However, if you’re a complete novice or cannot get your hands on such a software, then it’s better to find professional help.

Две проблемы с кодом ниже. Для начала я искал на этом и других форумах ответы на мой код ошибки 1784 года, и все, что я пробовал, провалилось. Два потока, которые я проверял на stackoverflow: WriteFile возвращает ошибку 1784 а также Ошибка ввода-вывода BlockWrite 1784. Я проверил некоторые другие на этом форуме, но я не помню точно, что сейчас.

Я пытаюсь сохранить массив структур в пустой двоичный файл. Первая проблема заключается в том, что я получаю нарушение прав доступа, если моя переменная размера (параметр nNumberOfBytesToWrite) меньше 99000 байт. Это число прыгает вокруг. Некоторое время, когда я тестировал, было бы нарушение доступа, если бы оно было 99,999 байт, но не 100 000 байт. Конечно, в конечном итоге я хочу установить размер всего массива. Исходный код для обработки, который теперь закомментирован, так что я могу тестировать с различными размерами.

Второе, что происходит (если я не получаю нарушения прав доступа), это то, что я получаю код ошибки 1784 и каждый раз происходит сбой WriteFile. Как заявили другие потоки в этой теме, это определено в MSDN как ERROR_INVALID_USER_BUFFER, а описание: «Предоставленный пользовательский буфер недопустим для запрошенной операции». Я посмотрел на собственный пример MSDN для открытия файлов, как это (http://msdn.microsoft.com/en-us/library/windows/desktop/bb540534%28v=vs.85%29.aspx) и попробовал некоторые варианты, основанные на их коде, но, похоже, ничего не работает.

Эта проблема, вероятно, в значительной степени нуб, и я уверен, что я пропускаю что-то смехотворно простое, но если у кого-то есть предложения, они будут очень признательны.

case IDM_SAVE1:
{
    HANDLE hFile = CreateFile("MineSave.mss", GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
    int test_buffer[] = {1,2,3,4,5,6,7,8,9,10};

    if(hFile != INVALID_HANDLE_VALUE)
    {
        BOOL bSuccess;
        DWORD size = 100000; //DWORD size = (((sizeof(tile)) * tiles_total));
        LPDWORD bytes_written = 0;
        bSuccess = WriteFile(hFile, test_buffer, size, bytes_written, NULL);
        if(bSuccess)
        {
            MessageBox(hwnd, "File saved successfully.", "Great Job!", MB_OK);
        }
        else
        {
            DWORD error = GetLastError();
            MessageBox(hwnd, "Could not write to file.", "Error", MB_OK);
        }

        CloseHandle(hFile);
    }
    else
    {
        MessageBox(hwnd, "Could not create file.", "Error", MB_OK);
    }
}
break;

Ваш буфер имеет размер 10 дюймов, что составляет 40 байт в Windows. Вы пытаетесь записать 100 000 байтов из этого буфера. Это неопределенное поведение, переполнение буфера. Отсюда и нарушение прав доступа.

Вы не должны передавать значение больше sizeof(test_buffer)т.е. 40к nNumberOfBytesToWrite параметр WriteFile,

Вам нужно будет записать этот файл в цикле, записывая 40 байтов за раз, пока вы не напишите столько, сколько вам нужно. Возможно, что-то вроде этого:

BOOL bSuccess = TRUE;
DWORD bytesRemaining = 100000;
while (bSuccess && bytesRemaining>0)
{
DWORD bytesToWrite = std::min(sizeof(test_buffer), bytesRemaining);
DWORD bytesWritten;
bSuccess = WriteFile(hFile, test_buffer, bytesToWrite, &bytesWritten, NULL);
bytesRemaining -= bytesToWrite;
}
if (!bSuccess)
{
//handle error;
}

Запись 40 байтов за раз довольно медленная. Вы найдете более эффективным написать несколько килобайт при каждом вызове WriteFile,

Обратите внимание, что вы не можете пройти NULL к lpNumberOfBytesWritten параметр, если вы также передаете NULL в lpOverlapped, как вы делаете здесь. От документация:

lpNumberOfBytesWritten [опционально]

……

Этот параметр может быть NULL, только если параметр lpOverlapped не равен NULL.

7

Вы должен предоставить буфер для получения количества записанных байтов, либо lpNumberOfBytesWritten параметр должен быть ненулевым, или lpOverlapped Параметр должен быть ненулевым.

Вы передаете NULL для обоих, что является незаконным и вызывает нарушение прав доступа.

Version 4.3.3

Please make sure that you reboot your computer after the installation of the RAM Disk application when it prompts you. This is an important step and should not be ignored.

Thank you! I had the same problem because I obstinately ignored what the app was telling me

This time round I did as told and everything is well.
