>Thanks for the answer, but I publish the update in Internet & I don't know which users are updated to VFP 8. My standart update procedure copies the new EXE and made all changes in Tables & DB I need. I want this procedure (writen in VFP 6) to check if VFP 8 not installed & start setup for it.

Hi Borislav,

The VFP8 runtimes can be installed into the application directory or some other place. You can find more about that at http://fox.wikis.com/wc.dll?Wiki~VFP8RuntimeFiles. Your check will depends where you want to put VFP8 runtimes for your application.
