Crystal Reports 8 export troubles in Windows7

I have
an older application which uses Cryst 8 and we use the activeX viewer. We turned
on the export button in the viewer. The export feature works on some machines
but on others it works up to the point of displaying the window that allows the
user to choose where to save the file. This window does not open at least on
some machines. What am I missing? I am desperate any help would be appreciated.
It works on XP but not in Win7.



Software:

Visual Studio 2003/C++ unmanaged
