After installing Spybot Search & Destroy 1.6.2 through allmyapps, I started Spybot and attempted to peform an immunization, but saw the following error, even though I was logged into an account in the administrator group when I started Spybot.
Error
You are missing administrator rights to perform this action.
If you need to do this, please run this application elevated as an administrtor.
When I started Spybot by right-clicking on its shortcut and choosing "Run as administrator", the immunization performed successfully.
