I installed Compatibility Pack for 2007 Office because I could not download a
WORD file in the 2007 version.

After that, I could open the word file BUT Excel and Power Point programs
would not open normally. The Window Installer comes on screen and is asking
for the original installation disks (Office 2003) which I do not have anymore.

I tried to restore the system but would not restore.

What do I do?
