To resolve this issue, enable the 8.3 file name creation functionality for files and folders on NTFS file system partitions:
  1. Start Registry Editor (Regedt32.exe).
  2. Locate the NtfsDisable8dot3NameCreation entry under the following key in the registry:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
    NOTE: By default, the value for this entry is set to 0.

  3. On the Edit menu, click DWORD, type 0 in the Data box, and then click OK.
  4. Quit Registry Editor.
  5. Restart your computer.
  6. Delete the Microsoft Firewall Client folder that is located in the Windows_folder:\Program Files\Microsoft Firewall Client folder.
  7. Reinstall Firewall Client.
