Hi, I have got a little demo in DirectX I want to show my friends, and it runs fine on my computer. It was developed in Visual Studio 2005 in C++, using the VC++ 2005 compiler. I also use DirectX 9 - the October 2005 SDK. On my friends computer it says "Configuration is invalid, this problem may be solved if you reinstall." Reinstall what?! Any ideas on this? I told him to try installing the DirectX 9.0C October redist, and he did and the same error occured. He didn't try a restart though for some unknown reason (apparently errors occur if he restarts *shrug*).
