>I've heard that Windows 2000 will restrict .DLL setup in the System Directory. Will this have any effect on Setting up VFP 6 apps on a client machine via the Distribution Wizard (which installs the runtime in the System Directory)? Will we need a patch to the Distribution Wizard?

Probably to the same extent that NT does now (on a properly administered NT system, only privileged users are allowed to write into the NT System directories...

If you build a Distribution using Setup Wizard now, installing on an NT system checks to see if you have admin privileges, and bails if you don't.
