  • Hi,

        Regarding this issue, if the key doesn't exist on your computer or deleting the key doesn't help, try these two steps below.

    Step 1: Disable User Account Contro (UAC)

    1. Open User Account Control Settings by clicking the Start button, and then clicking Control Panel. In the search box, type uac, and then click Change User Account Control settings.
    2. To turn off UAC, move the slider to the Never notify position, and then click OK.
    If you're prompted for an administrator password or confirmation, type the password or provide confirmation. You will need to restart your computer for UAC to be turned off.

    If turning off UAC doesn’t help, enable it back and go to step 2.

    Refer:

    Turn User Account Control on or off
    http://windows.microsoft.com/en-US/windows7/Turn-User-Account-Control-on-or-off

    Step 2: Disable all your security softwares

    Disable all the security softwares. Once the security softwares like any firewall are disabled, try opening the progams and see if there’s any noticeable change in the behavior.
    If the problem goes away then it’s most likely the firewall settings that is preventing you from accessing programs.

    Step 3:Change the Internet Options

  • You probably have messed up the registry.

     

    Insert your Windows disk and boot from it and select repair

  • I should mention that Windows has a firewall included, so a 3rd party one is not needed.

    Downloading and running the hotfix should suffice. Ignore the "Workaround" part.
