Thanks for the info! Can one of you do a little test for me?

The old version, 7.07, contained 6 DLLs in the folder:

mfc80, msvcp80, msvcr80.dll

and

mfc71, msvcp71, msvcr71.dll

Can you, just for testing, temporarily remove first the 3 "..80", and then the 3 "..71" DLLs from the installation folder, and test whether the problem appears again after the first or second removal?

The DLLs are the Microsoft MFC Dlls and they are supposed to be automatically installed to the Windows System folder - Version 7.10 contained a Microsoft merge module for this. Apparently, the merge module did not fix the DLLs on your PC and your test would give me a hint which part did not work. Maybe some DLLs of the same name, but faulty versions were installed by some other software in your Windows system folder.
