Lately we discovered a problem at one of our customers when trying to register the McAfee AntiVirus Plus 2009 package. The registration process (as with several other McAfee users) doesn't seem to work properly. We have noticed that most of these cases are caused bij the fact that they have had an older version of Mc Afee Virus Scan installed on the computer before.
Yes, it's a fairly well known issue.. ALWAYS uninstall the previous version of VirusScan before installing the new version.. Don't depend on the new version to correctly identify or correctly uninstall the previous program.
The correct uninstall process depends entirely on the previous version of VS.. There are correct uninstall instructions for such we'll need to know the specifics of the old version.. Version number, retail or corporate, etc. For retail versions, doing a little research for the MCPR.exe removal tool might help.. As to the corporate versions, we'll need the version number to provide the manual removal instructions.
