>How have you folks out there handled removing the VFP5 run-time engine and associated installed components from a user's machine AFTER you've upgraded your apps to VFP6 and redistributed the new VFP6 runtime engine? Or have you handled it at all?

Moving from VFP3 to VFP6. I didn't bother. The runtimes don't seem to conflict at all. Hard drive space is generally cheap and plentiful.
