Symptoms

MAC users cannot launch applications and receive the following error message(s):

“Error in connection file ‘/Users/UserName/Library/Preferences/Citrix ICA Client/Modules’: Cannot find section ‘SmartCard’”.

Error number 11

“Cannot write connection file ‘/Users/…’ ”

Error number: 30

Causes

This issue occurs when "SmartCard, " is included in the Modules file of the ICA client on MAC client workstations.

Note: This issue has also been reported with SSPI instead of SmartCard.

Resolutions

1. Open a text editor.

2. Browse to File-> Open > Users/myName/Library/Preferences/Citrix ICA Client/Modules

3. [Optional but recommended:] Make a copy of the Modules file and rename it something else.

4. Delete the Modules file and restart to have the system recreate a fresh new Modules file can also fix this issue.
