Ohhhhhhhh...  what components are missing?

Please try this:  reboot your machine and then run the FOVSetup again.   Sometimes we get stuff hung in memory and it takes a reboot before the install to work properly.   Also, what OS are you running.   We only support Win2K and newer, and I don't know what it does on Vista... we don't use it in our daily work yet.

I haven't tested the install on a perfectly clean machine for months.   I'll try to do so this afternoon.
