Associating the ICA file type with Virtual Office CS or SaaS applications

Alerts and notices

In some cases, Windows is unable to open applications in the Virtual Office CS or SaaS environment because it doesn’t recognize the ICA file type or because the file has been damaged. The error message that contains this information is issued by the application that is currently associated with the ICA file. For example, you might receive an Adobe Reader error that states, "Adobe could not open application.ica because it is either not a supported file type or because the file has been damaged."

To fix this, you must change the default application associated with the .ICA file extension.

Windows 8.1

  1. Open the Control Panel.
  2. Choose Default Programs.
  3. Choose Associate a file type or protocol with a program.
  4. Find .ica in the list of file types.
  5. Click the Change program button.
  6. Choose Citrix Connection Manager from the Recommended or Other Programs section.
  7. Click OK.

Windows 10

  1. Open the Control Panel.
  2. Choose Default Programs.
  3. Choose Associate a file type or protocol with a program.
  4. Choose default apps by file type.
  5. Find .ica in the list of file types and then click the current assigned Default app.

    If .ica is not in the list of file types, you'll need to install Citrix.

  6. Choose Citrix Connection Manager.

If you receive the error message "This version of Citrix is already installed" when trying to launch an application, make sure the default is set to Citrix Connection Manager rather than Citrix Receiver.

Note: If Citrix is not available, you need to navigate to and select wfcrun32.exe.

  • If you’re running a 32-bit operating system, browse to C:\Program Files\Citrix\ICA Client.
  • If you’re running a 64-bit operating system, browse to C:\Program Files (x86)\Citrix\ICA Client.
  • If you cannot browse to this location, right-click on a file with the .ica extension and choose Open With to browse to the above location of the wfcrun32 file.
