I previously installed MSOfficePro2007 on 3/6/2010 but due to MS Update
problems with my PC I had to remove it (and many other programs) via
Add/Remove Programs in the Control Panel. You would think it would
re-install without a problem if I removed it the 'correct' way! I get this
message (without an error number) :
Microsoft Office Professional 2007 encountered an error during setup.
Only option offered was: Close
The gurus want a PID number but if it isn't installed you cannot locate one!
Thank you
