File associations in isolation environments and published applications

If you use Presentation Server 4.0's new “Isolation Environment” feature you will discover that the newly installed applications do not create any file associations. If you publish a desktop, rather than applications you will find that data files will not be associated with the application and will display just a generic windows icon. If a user double-clicks at the data file they will receive the “Open With” dialog box.

You can easily fix this issue by using some simple commands of assoc and ftype while logged on as Administrator. These instructions have been tested with Windows 2003 and PowerPoint 2003


  1. Open a CMD Prompt
  2. Type:

    assoc .ppt=PowerPoint

  3. Type:
    ftype PowerPoint=”C:\Program Files\Citrix\System32\AIERun.exe” “Office2K3″ “c:\Program Files\Citrix\AIE\Office2K3\Device\C\Program Files\Microsoft Office\OFFICE11\POWERPNT.EXE” “%1″


    The speech marks around “%” are important because without them you will have problems double-clicking at long file names and files with spaces.

    This will fix the association, but it will still have a generic window system icon. To fix this

  4. Open the File Types dialog box
  5. Locate PPT
  6. Click Advanced
  7. Click Change button
