I installed win2000 yesterday - it went fine, and when I started installing programs - Photoshop, zonealarm and the likes, I get a pop up message box which says:
(FileName varies)
FileName.exe - No Disk
X There is no disk in the drive. Please insert a disk into drive A:
Cancel Try Again Continue
But I'm not intsallin gfrom the A drive at all. Then if I hit Cancel or Continue, it skips the file and continues to install.
Once done installing, when I open (some of) the programs, this same message pops up and I have to Cancel through it and the programs open.

What's going on - and what's the fix??
