Symptoms

You have a computer that is running a 64-bit edition of Windows 7 or Windows Server 2008 R2. You run a 32-bit version of an application that uses the QueryPathOfRegTypeLib function to retrieve the path of a registered type library. However, the QueryPathOfRegTypeLib function does not return the correct path. The path of the 64-bit version of the type library is returned instead of the path of the 32-bit of the type library.

For sample code to reproduce this issue, see the "More information" section.

More Information

Sample code to reproduce this issue

For example, the following sample code develops a 32-bit version of an application:
#include "windows.h"
#include "Oleauto.h"

int _tmain(int argc, _TCHAR* argv[])
{
        GUID guid;
        //OLE Automation(2.0)
        IIDFromString(L"{00020430-0000-0000-C000-000000000046}", &guid);

        DWORD lcid = 0x0409;
        BSTR str;
        QueryPathOfRegTypeLib(guid, 2, 0, lcid, &str);

        wprintf(L"%s\n",(LPCTSTR)str);

        ::SysFreeString(str);
        return 0;
}
When you run the application in a 64-bit edition of Windows 7, you expect to receive the following output: 
C:\Windows\SysWoW64\stdole2.tlb 
However, you receive the following output:
C:\Windows\system32\stdole2.tlb
