So I tried moving my project to Visual C++ Express 2010 on Windows 7 from a previous version on Windows XP. I got all sorts of errors where atlbase.h was not found. This isn't so much a question but I wanted to document what my resolution was for others. Copied the following PlatformSDK files from my previous install and put them on my Windows 7 machine. PlatformSDK/include/atl PlatformSDK/include/mfc PlatformSDK/lib PlatformSDK/src/atl I then change the VC++ Directories in the project Properties to point to those directories. Include Directories- *include/atl *include/mfc Library Directories- *lib Source Directories- *src/atl Make a change to stdafx.h right after this line: #include "atlbase.h" add this line: extern CComModule _Module; Hopefully you're ready to go now! Probably not but perhaps you are well on your way.
