I think I know what the problem is. The cab file I'm trying to extract has directories inside. I think when CabExtractCallback is called for the first file we get wzPath pointing to a string like C:\Users\user\AppData\Local\Temp\extract\subdir\file1.txt and the call to CreateFileW fails because C:\Users\user\AppData\Local\Temp\extract\subdir does not exist yet. I think this results in GetLastWin32Error returning ERROR_PATH_NOT_FOUND back in CabOperation which converts the error into 0x80070003 which then gets returned to CabExtract and finally back to me.
If my guess above is correct, then the fix is to ensure the directory portion of wzPath exists before calling CreateFileW.
