4. Click the Version tab and confirm the file version.
   
   • If the file is version 17.1.51.0 or higher, but less than 17.1.219.18, then proceed with this installation.
   • If the file is less than version 17.1.219.0, then you must first install AutoCAD 2008 SP1.
   • If the file is version 17.1.219.18 or higher, then this hotfix has already been applied.

   • In the Autodesk Shell Extension folder, right-click the file AcLauncher.exe and rename it AcLauncher.bak.
6. Based on the version of your product, double-click AcLauncher_32bit.zip or AcLauncher_64bit.zip.
