You click to launch your applications in Google Chrome and the application does not launch. Instead, you see a launch.ica file downloaded from Google Chrome or the launch.ica file is opened up by some incompatible program on your computer (such as by another web browser or a Microsoft Office application).
The launch.ica file is a Citrix file used by your web browser to virtualize your Citrix applications. This file is usually downloaded silently from Chrome and opened automatically by the Citrix application installed on your local computer. However, a recent update to Chrome has changed this usual process.
Google released the Version 42.0 update to Chrome on April 15, 2015. As a part of this update, Chrome now handles certain web content differently. For Citrix , Instead of downloading and automatically launching the launch.ica file like in the past, Chrome now just downloads the file instead. Depending on other local settings, your computer may try to automatically open the launch.ica file with an incompatible program as well.
Most users have Chrome set to update automatically, hence your Chrome may have already updated to the latest version without your knowledge.
To resolve, we need to tell Google Chrome to continue to automatically open the launch.ica files instead of just download them.
If the above changes did not resolve your issue, then the Google Chrome update may have affected the default program that your computer uses to open .ica file types. As a result, you need to adjust the default program that opens .ica files on your local computer.
