I looked at the other solutions for this error code and none worked. I just installed Windows 7 on my PC that was runnign XP. It worked great and I installed all my applications. Two days after I installed it I got a notification that my firewall was not on. I went to turn it on and it won't let me. I tried repairing it and troubleshooting and it didn't help at all. I still have the problm. My setting is on Automatic and I can not manually turn it on. HELP!!!!
