Solution for "Has Not Been Installed for the Current User" - this is the fix!
This has happened to me twice in the last year or so, once after running a
registry cleaner, and another time after running a "unnecessary file cleaner". :?.
All my MS Offic apps (Excel, outlook, Work, Powerpoint, Publisher) would not
run but prompted (program) "as Not Been Installed for the Current User"
Arrgh! Here is the fix that worked for me:
Go to control panel, add remove programs icon,
select the 'change or remove" option,
then select MS Office 2003
Then click the link "click here for support information".
Then click the "repair" button.
I put my installation DVD in drive but was propted to browse to a folder that contained "PROI11N.MSI"
I searched and found this file in a hdden folder C:\MSOCache\All Users\90000409-6000-11D3-8CFE-0150048383C9
Was prompted to wait while Windos configure MS Office.
All MS Office applications then functioned (no reboot or CD key entry needed).
Note that Outlook prompted that it detected a new account and whether I wanted to import it.
I declined as i could already see my emails.
Life is good again.
