When passing an ICA file to wfcrun32.exe from the command line and the ICA file contains the lines:

• InputEncoding=ISO8859_1
• ConnectionBar=1

CDViewer.exe version 11.2x might exit with the error system.IO.InvalidDataException.

To resolve the issue, edit the ICA file:

1. Open the ICA file.

2. Search for the following line in the file:

3. InputEncoding=ISO8859_1

4. Replace with the following value:

   InputEncoding=UTF-8

5. Save the ICA file.

Problem Cause

The issue occurs because of the wrong encoding being specified in the ICA file. Citrix does not use ISO8859_1 encoding with the desktop viewer.
