No, it will not tun on Windwos 7. You will have to use McAfee VirusScan 8.7i. Make sure that you get the one that has at least Patch 1 packaged into it. I have been using VSE 8.7 with Patch 1 on Windows 7 64-Bit with no issues so far. McAfee won't fully support VSE 8.7i until Patch 2 is released in the next few weeks.
