Unity Web Player problems

I keep getting a error sayign i must install manually. But after i do that, it doesn't. I think the issue is my antivirus software blocking it. Anyone have any problems with Trend Micro blocking the update of Web Player?

I had that problem bring 2.6 into 3.2. Reinstalled til the cows came home, no luck. The only thing that did work was going into RegEdit and nuking all the unity web player things I could find, and deleting the files too. Then it reinstalled just fine.

okay so regedit. but how do you find all the unity web player stuff?? Is there a list?

okay so which files are looking for in regedit for unity?
