After an .ica file has been downloaded during a launch attempt from browser, the following messages appear on the screen.

"Please wait while Windows configures Online Plug-in"


"Fatal error during installation"


An error message such as below might be logged in Event Viewer on the endpoint machine:
"MsiInstaller",1001,"Detection of product '{51059DCA-191F-49CD-8A37-FE5516EA52C9}', feature 'WEB_CLIENT' failed during request for component '{1762F5BA-3F32-4A41-90CB-83C447BE6ED2}'"

1. Re-install Citrix Workspace app on the affected machine.
2. If the issue persists, check the existing file association for the .ica format.
   • Start Command Line as Administrator and execute the following command:

     assoc .ica

   • Copy the part of the output after ".ica =" and run the ftype command against it, e.g.: 

     ftype Citrix.ICAClient.2.16

3. Check if wfcrun32.exe is present in the location that was returned by the above command.
4. If the path is correct, create a new file type association for .ica by executing the below command. 

   ftype Citrix.ICAClient.2.16.NEW="C:\Program Files (x86)\Citrix\ICA Client\wfcrun32.exe" "%1"
   assoc .ica=Citrix.ICAClient.2.16.NEW

Problem Cause

.ICA file association might have become corrupted on the machine, even if it appears intact in registry.
