Virtual Client Office

Associating the ICA file type with Virtual Client Office applications

In some cases, Windows is unable to open applications in the Virtual Client Office 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.
