Microsoft Office 2003 not opening after a PC reboot

Hello all,
I installed Office 2003. Restarted my computer and clicked on the outlook icon, and an error message said; “Cannot start Microsoft Office Outlook. MAPI32.DLL is corrupt or the wrong version. This could have been caused by installing messaging software. Please reinstall Outlook.” Please see the screenshot.
I reinstalled it a few times and it said the same thing.
What’s wrong here?
Need your help.
