I'll try and remember a tool called Dependency Walker.

Dependency Walker claim MSVCR80D.DLL is missing if I try to open t7.dll second release. If I open the first release of t7.dll this file is not missing/used.

DirectX version 9.0c (4.09.0000.0904) I have tried -diag and it does not show t7.dll being loaded/opened with A7.06.1 on this computer.
