Net framework общая ошибка доверия

I’m having the same issue as a lot of other people.  I’ve downloaded the standalone installed for the .Net Framework 4 (dotNetFx40_Full_x86_x64.exe) and tried installing it both by simply double-clicking the executable and right clicking > Run as
Administrator.  Neither are working, they both give the same error, «Generic trust failure.»  I’ve gathered my logs and uploaded them to my personal site, they are located here:

http://infectionist.com/misc/vslogs.cab

I guess the installer chose my H: drive as the file xtraction drive, since it’s the largest fixed drive (well, the most free space.)  Here are a few lines from dd_dotNetFx40_Full_x86_x64_decompression_log.txt:

[6/25/2010, 10:24:15] Drive 'H:\' has been selected as the largest fixed drive
[6/25/2010, 10:24:15] Directory 'H:\d1f8e660ffe46cc42cb6\' has been selected for file extraction

[6/25/2010, 10:24:23] Executing command line: 'H:\d1f8e660ffe46cc42cb6\\Setup.exe  /x86 /x64'

Then I took a look in the .net installer-generated HTML log file, and the lines of interest are at the very bottom:

I notice a few things.  First, «Possible transient lock.»  What does that mean?  I disabled my antivirus (I use AVG 9 Free) and tried again with the exact same result.

Another thing, «No filehash provided.»  I’m not 100% sure what this means, but I know that if I right click the SetupUtility.exe and click properties, go to the Digital Signature tab, there is a Microsoft signature there.

Also, on the second line from the bottom, the path is shown as «-H:\844a21f445080c9a4dc33238fb\SetupUtility.exe», why would it put a minus sign in front of the path?

Finally, last line, it tells me to delete the file and try the installation again.  Knowing that that was a stupid request, but wanting to get the issue resolved, I tried a few things.  First I tried simply renaming it to SetupUtility_.exe, then
I tried replacing it with the SetupUtility.exe that I had gotten from an extract of the package, and finally I tried actually deleting it.  None of these things worked, it still tried to verify it, it still failed with the same errors, even though the
file was not there.

Funny thing is, I had this installed and I accidentally uninstalled it when I was uninstalling Silverlight 4 stuff, now I can’t get it back.

Oh, I also tried the .Net Framework Cleanup Tool here:

http://blogs.msdn.com/b/astebner/archive/2008/08/28/8904493.aspx

And it successfully removed whatever was left of the .Net Framework 4.  This is getting really really frustrating.  Without this I can’t debug in Visual C# 2008 (for some reason) and I can’t do anything in Visual C# 2010.  I need those programs
to work.

I tried to install .NET Framework 4 on Windows Server 2003, but got this error message «Generic trust failure».
