This is the problem with using AxtiveXs in FTView. Many Microsoft apps, such as Office update Fm20.dll. The other machine without Office can't use the newer DLL.
We faced this exact problem also. It appears that there is a conflict with updates made to two DLL files.
To resolve this issue we completed the following:
Retrieve FM20.DLL and FM20ENU.DLL from the RSView32 machine.
Copy to C:/Windows/System32 (May have to overwrite existing files).
Register the FM20.DLL using and elevated CMD and regsvr32 command.
