>I want to install vfp 9 sp2. I can do this. Have any problem in this sp.

The most reliable way to install SP2 is to uninstall VFP9, re-install it and apply SP2.

Check Bo's blog at http://blog.moxiedata.com/CategoryView,category,SP2.aspx about SP2 bugs. YMMV with SP2.

There're 2 hotfixes released. See http://www.berezniker.com/content/pages/visual-foxpro/vfp-90-versions. You'll have to contact MS support to get them.

See http://rickschummer.com/blog/2008/03/vfp-9-rtmsp1sp2-one-machine.html if you want to have VFP9 SP1 and SP2 on the same PC
