I'm just another home user, and I haven't yet had the occasion to uninstall/clean/reinstall McAfee from this Vista box, but you might wish to check out Peter's detailed steps in this thread:
As I understand it, the MCPR tool is only designed to clean traces left after a Windows add/remove programs uninstall. IOW, you don't use the MCPR tool to actually uninstall the McAfee program. And, you need to reboot at the appropriate times. And, as Peter suggests, you need to check Windows Explorer after running the MCPR tool to be sure all the McAfee folders (even the empty ones) are gone.
I suppose you could also try running Revo Uninstaller, which is a free, standalone utility that helps to remove traces of uninstalled programs.
You might wish to wait for Peter, Dinz and the other mods/mentors/experts to weigh in, but trying Peter's steps precisely as he describes them ought to work.
Hope this helps,
Are you running the latest version of MCPR from the Useful Links menu above? Also are you trying to remove recent home products? This tool will not remove any McAfee Enterprise or Business products.
If that doesn't work then you'll have to try the long way or contact Technical Support Chat.
Enable Windows Firewall while you are unprotected by McAfee.
The regedit procedure can be done offline anyway.
Go to Start/Run and enter regedit and click OK.
A page should open with the top left hand corner looking like this:
if for some reason it's expanded, collapse it and then highlight My Computer (Computer in Vista).
Go to File tab and click "Export" and send all of the registry to your desktop. This is in case something goes wrong. It can then be rebuilt by simply double-clicking that desktop item.
Now click the Edit tab and then "Find". Enter "McAfee" (minus the "") then click "Find next" (or hit the enter key).
Whatever is found, right-click and delete.
Hit your F3 key for the next instance and keep going until all entries are gone.
If one says it can't be deleted this is where it gets complicated. You have to then find which key on the left column pertains to it and right-click/Properties/Permissions and give yourself permission.
If that happens stop and let me know if you aren't sure of what to do.
If all is successful that VS7 entry could not possibly remain and you can then delete the registry backup.
This has to be done when signed in as an Administrator by the way.
You may have to repeat it using "Network Associates" and/or "NAI" minus the "" - it can be a long process.
If this is about business products then you should be posting in the business section.
Well, it is fully compatible with Vista and Windows 7 for that matter so not too sure what is the problem unless the product remnants are from some really old version or, as I said above, from a version other than the home (Consumer) products.
Is this causing a problem with something else? I'm sorry but unless my registry removal method posted above helps I suggest you contact Technical Support Chat and give them your MCPR log zip to analyse.
It has never failed me in Vista Ultimate x64.
