yes 9.0 is not supported i am attaching some info on it.
do you have access to the mcafee website and do you have a userid with them?
I am assuming that they will let you download a newer copy from there, but that
is an assumption only.

As Bmoos says, a reinstall should get you version 9.15 which is Windows 7 (x86 and x64) compatible.
Try the following:
1. Uninstall all McAfee programs through "Add or Remove Programs" in Windows "Control Panel".
2. Use the MCPR tool, see this article: How to remove supported McAfee consumer products using the McAfee Consumer Products Removal tool (MCPR.exe). This will remove all McAfee remnants from your computer. (You must have Windows 7, Vista, XP or 2000, SP4 to use this tool)
3. Launch Windows Explorer and delete all McAfee files in "Program Files" but especially in "C:\Document and Settings\<user>\Application Data" and "C:\Document and Settings\All Users\Application Data". You have to set Windows Explorer to show all hidden files and folders (Tools > Folder Options > View tab). Just delete the McAfee folders even if they are empty in all the "Application Data" folders. Can be more than one!
In Vista: C:\Program Files, C:\ProgramData and C:\Users\yourname\AppData\Roaming
If you can't find these files don't worry. It just means that MCPR has done its job.
4. Reboot and redownload/reinstall your McAfee products directly from your account at the McAfee web site.
If you are McAfee direct customer, go to https://home.mcafee.com/Secure/Protected/Login.aspx and log in to download your McAfee products.
DELL users should go to https://uk.mcafee.com/root/login.asp?affid=105 and log in to download your software.
