The first time I got this error was when I tried downloading a Java update. It could not continue because "Error 1606, could not access network location". Later, I started cleaning up my PC and uninstalling shit when I got the same error trying to uninstall C&C 3. I looked it up, but all the websites that offer software to fix it are rather dubious and try and make me register. I've run CCleaner and TweakNow Powerpack multiple times. Does anyone else have any ideas? Besides reinstalling Vista?
