To get the version of any module, you can use http://support.microsoft.com/default.aspx?scid=kb;en-us;167597 ("SAMPLE: GetVers.exe Specifies Component FileVersion and #Version"):

#include <windows.h>

   void reportError()
   {
       LPVOID lpMsgBuf;

       FormatMessage(
           FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM,
           NULL,
           GetLastError(),
           MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
           (LPTSTR) &lpMsgBuf,
           0,
           NULL );

       cout << (char*)lpMsgBuf << "\n";

       // Free the buffer.
       LocalFree( lpMsgBuf );
   }

   void main( int argc, char *argv[ ], char *envp[ ] )
   {
       cout << "\n";

       if(2 != argc)
       {
           cout << "Syntax: GetVer <File Name>\n";
           return;
       }

       DWORD dwArg;
       DWORD dwInfoSize = GetFileVersionInfoSize(argv[1], &dwArg;);

       if(0 == dwInfoSize)
       {
           cout << "No version info available\n";
           reportError();
           return;
       }

       BYTE* lpBuff = new BYTE[dwInfoSize];

       if(!lpBuff)
       {
           cout << "Out of Memory\n";
           return;
       }

       if(0 == GetFileVersionInfo(argv[1], 0, dwInfoSize, lpBuff))
       {
           cout << "Error retrieving version info\n";
           reportError();
           return;
       }

       VS_FIXEDFILEINFO *vInfo;

       UINT uInfoSize;

       if(0 == VerQueryValue(lpBuff, TEXT("\\"),
               (LPVOID*)&vInfo,
               &uInfoSize))
       {
           cout << "Version information not available\n";
           delete lpBuff;
           return;
       }

       if(0 == uInfoSize)
       {
           cout << "Version information not available\n";
           delete lpBuff;
           return;
       }

       cout << argv[1]
           << " Version: "
           << HIWORD(vInfo->dwFileVersionMS) << ","
           << LOWORD(vInfo->dwFileVersionMS) << ","
           << HIWORD(vInfo->dwFileVersionLS) << ","
           << LOWORD(vInfo->dwFileVersionLS) << "\n";

       delete lpBuff;
   }
