I have the Windows 7 64 bit edition here and I have seen that I simply cannot have the things to work in the proper manner here. When I was running Windows XP I was not having any issue there; but when I try to go with Windows 7 I have seen this issue with me here. I have seen that I cannot simply turn on Windows firewall here. I have seen that I get a error code 0x6D9. I have been on the Internet to see if there can be anything that can help me in turning ON the Firewall here.
