Нам сообщают, что какая-то из версий уже установлена, и чтобы установить новую, сначала нужно удалить старую.

Первым делом проверьте, не установлен ли у вас в системе Microsoft Visual C ++ 2017. Если он присутствует в Windows, то удалите его и попробуйте провести инсталляцию Visual C ++ 2015. После этого поверх 2015 установите 2017. Часто данный метод помогает.
