This problem may occur if the number of installed network filter drivers exceeds the specified limit. You need to check if the Network Filter Driver limit has been reached.

 
By default, Windows 7 has a limit of 8 and a maximum allowable limit of 14.

To resolve the issue, increase the Network Filter Driver limit so we can install the Firewall driver:

  1. Click Start > Run.
  2. Type "regedit" and then click OK.

     
    Always back up the whole registry before making any modifications. Incorrect changes to the registry can cause serious system problems.
  3. Locate and then click the following registry subkey:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\

  4. On the right pane, right-click MaxNumFilters and then click Modify.
     
    If the registry key does not exist, manually create it.
  5. Select the Base Decimal option, change the value to decimal 14 then click OK.

     
    The default value is 8 and the maximum value is 14.
  6. Close the Registry Editor.
