Studio User Guide
This page explains how to fix issues you might encounter when running automation in Citrix environments.
Observed Behavior
After you install the UiPath Extension for Citrix and try to select UI elements from a Citrix App, interactive selection freezes for one minute, and then nothing is selected.
Cause
This happens if the UiPath Remote Runtime is not running in the Citrix App session.
Solution
- Check if the UiPathRemoteRuntime.msi is installed on the Citrix application server from which the Citrix App is opened.
-
On the Citrix application server, check if the UiPathRemoteRuntime.exe process is running. If the UiPathRemoteRuntime.msi is installed, then the process is started automatically on the Citrix App session login.
Note: If you can not install the UiPathRemoteRuntime.msi on the Citrix application servers, it is recommended to uninstall the UiPath Extension for Citrix from the client machine, as described here.
Could Not Copy Over File "C:\Program Files (x86)\Citrix\ICA Client\UIPathPluginCitrix.dll". It Is Being Used by Another Process.
Observed Behavior
When you try to install the UiPath Extension for Citrix, the following error is displayed:
Cause
This occurs when the UiPath Extension for Citrix is already installed and an open Citrix App is using it.
Solution
Close all your active Citrix App sessions, as described and then try to install the UiPath Extension for Citrix again.
Observed Behavior
When you try to install the UiPath Extension for Citrix, the following error is displayed:
Cause
This error message is displayed when the Citrix Receiver is not installed. It is also displayed if the Citrix Receiver for Universal Windows Platform is installed.
Solution
Download and install the Citrix Receiver or Citrix Workspace.
Observed Behavior
Target Citrix App fails to launch and the Citrix ICA client crashes.
Cause
Activities which use the GetWindowText function (such as Element Exists) are executed before the Citrix App can load.
Solution
Allow time for the Citrix App to load by adding a delay before the activity.
