Is there a way to cancel an installation of a program before shut down. I accidentally installed Fortress on my computer and before it completed, I hit cancel and escape but it still asked me to setup a password which I didn't, and then it said it would try to configure anyway after bootup. I want to cancel all installed items of Fortress before I shut down. I know Fortress is a real mother to get rid of once it gets installed. I deleted all temp files, but I'm sure there are other things I have to do. Please help!!!
