I know the support article located at http://seer.entsupport.symantec.com/docs/287937.htm says I have to uninstall the old version of MAPI/CDO before I install the new version for the upgrade to be successful, but I can't find instructions on how to uninstall the old version. Can somebody help out?
Andrew, just go to Add/Remove programs and it will be in the list... It is called "Messaging API and Collaboration and Data Objects 1.x.x" (Acronym is MAPI CDO) :)
Just uninstall, reboot and install the newest version.
