I got a new computer at Christmas (Acer laptop with Windows Vista, I use Mozilla Firefox for internet) and it had a trial version of the Security Suite. My trial period just ended so I went online and renewed my subscription, downloaded the software and attempted to install it. The Installer started "gathering information" and then the box went blank and nothing happened for hours - I just let it run. I tried installing again in safe mode. Same thing happened and then finally I got a message that "Installation Cannot Continue" and that updates had been made to the installer and a new version is available. There was a button at the bottom of the box to "use new version" but it wouldn't let me click it. This was just hours after I had downloaded it! How can I get my Security Suite to install???
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 find none do not worry, as it only means that the removal tool has done its job.
4. Reboot and redownload/reinstall your McAfee products directly from your account at the McAfee web site, not from any CD that you may have.
