Recovering the .sky File Extension Association


If you end up in a state where you can no longer double-click in the Windows Explorer on .sky or .skyd files and have Skyline open the files for you, do the following:

  • Run regedit.exe and delete the following keys if any are present (they may not all be)
  • Delete the keys HKEY_CLASSES_ROOT\.sky and HKEY_CLASSES_ROOT\.skyd
  • Delete the keys HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.sky and .skyd
  • Delete the keys HKEY_CLASSES_ROOT\Skyline.Data.0 and HKEY_CLASSES_ROOT\Skyline.Document.0
  • Reboot your computer
  • Wait for an update or reinstall Skyline (see also Recovering From a Broken Installation)
