Windows installer keeps popping up.

(moved from office.misc newsgroup) (also moved updates I found)

WinXP, Office 2k(pro). all updates

Tried to open Word this morning and get this error msg. This lead me to try

and open other Office products with no luck except Publisher.

(Windows Installer)

"The installation source for this product is not available. Verify that the

source exists and you can access it."

This is a system that has worked fine for 4+ years.

Can't open Excel, Access, Outlook, Powerpoint using Program- Word, etc.or

Frontpage but I can open Publisher!!

When I inserted O2k disk it doesn't auto open so I go to setup.exe and get

the same error msg. as above.

I've also tried to "Detect and repair" but get error msg "The installation

for this product is not available. Verify that the source exists and that

you can acces it." See update #2 below..

Thanks

update 1: When I open OLE I get a screen that states Window Installer-

"preparing to install". The only option I have is to "cancel" but it does

finally go away on it's own.

update 2: If I go to C:\Program Files\Microsoft Office\Office I can open

Word,

Excel, etc. and create another shortcut on desktop to open program but I

still can't use "Detect and Repair".

Hope this isn't too confussing.

Any comments/suggestions PLEASE,
