>I recently reinstalled VFP 7.0 to test some backwards compatibiliy issues. Before hand, I had 8.0 installed. Now all the VFP related files are assicated with the 7.0 version. I am tring to reassociate them back to 8.0. I have tried the /RegServer command line option, but that did work. What am I missing?

Try

vfp7.exe /unregserver
vfp8.exe /regserver
