I have a young lady friend who has an older Nancy Drew game available which played OK on W7 but the newer game aborted with a directx error. I noticed that the directory structure between the installed games was identical and got an idea. The following is NOT recommended for a novice. I am only trying to demonstrate that games giving a directx error likely have nothing mai samar car do with directx and more likely have an issue with the Installshield installer.
I read with horror that someone had tried to delete every directx-related file from the registry in order to reload directx 9.
Если вам не удастся запускать абсолютно аналогичный показанному на платформе, вам снова придется раскошелиться процедуру. Последовательно допускаете ошибку и вы проиграете.
You may be able to uninstall it with programs dedicated to that, like CCleaner. Also be aware, that I know how to remove remnants of any program in the registry so I was not worried about leaving traces of the old installation around.
