MAPI32.DLL corrupt errors when I launch Outlook 2003

[LUNCHMONEY]

I am trying to fix an XP Home Edition computer on which Outlook was recently
re-installed to try and remedy a DLL launch error. All user accounts on the
system (three accounts) receive the following error message when launching
Outlook:

Cannot start Microsoft Outlook. MAPI32.DLL is corrupt or the wrong version.
This could have been caused by installing other messaging software. Please
reinstall Outlook.

I have also tried running "C:\WINDOWS\system32\fixmapi.exe," but to no
avail. ANY NEW SUGGESTIONS / IDEAS?

 

[Diane Poremsky [MVP]]

did you try Help, Detect and Repair?

Cannot start Microsoft Outlook. MAPI32.DLL is corrupt or the wrong
version. This could have been caused by installing other messaging
software. Please reinstall Outlook.

And if Diane's suggestion doesn't work, try renaming that DLL to .OLD and
restarting Outlook.

To Diane & Brian - I will have an opportunity to verify both approaches
tomorrow, and let you know if either remedies the problem. Brian's
suggestion was - ostensibly - already tried, and did not succeed.

Thank you both!
