You should upgrade RF before you try to run RF.
So you probably should uninstall and then reinstall
before updating. When you uninstall, you should go
to Windows/common files/ and delete the KE directory
to be sure that you get a good install.
Now reinstall and if possible let RF use the default
directories.
Reboot and put the RF disk back in the drive,
When you are prompted by the menu pick update
and continue after you get to the update site.
After update is complete, try running RF and if
we're lucky it will run just fine.
If not post more info and let us know what the new
error messages are and we'll try to help.
I fly everything there is. I crash all that I have. (Sometimes) And I always pick up my trash.
