File version information under NT

I am using the GetFileVersionInfoSize, GetFileVersionInfo, and VerQueryValue APIs to get the file version of third-party applications. In all cases, GetFileVersionInfoSize returns a large number, but when I query it for StringFileInfo40904B0ProductVersion, sometimes I get nothing. My Visual Basic application and my C++ DLL both return values, but Excel and Visio return nothing. Any thoughts?

Not a direct answer, but if you are doing this from multiple envioronments, wouldn’t it be easier to create an ActiveX exe which returns this information, and then use it from all your programs? Write it in either Visual Basic or C++; both do a good job with this kind of stuff. Then you don’t have to worry about what different things you need to do in Excel, Visio, or whatever. Little utility packages like this can be incredibly useful and have a quick payback.
