I am using a fresh install of Windows 7 64bit edition. I was previously using Vista 32 bit. Both times I was just using the default version of DirectX which came with Windows, which was version 10 for Vista and 11 for 7.
I am using the latest drivers for my video card, a radeon mobility 3650. On Vista 32bit, I installed IGI 2 and played it without a problem. I can not get it to run on Windows 7 at all. Whatever I try, compatability mode, different drivers, DirectX versions etc, I only get the error message "This application requires DirectX version 8.1 or higher".
Even searching for this error message returns only about 3 or 4 other, non-resolved similar problems. Does anyone have any suggestions?
