Citrix Extension troubleshooting
This page explains how to fix issues you might encounter when running automation in Citrix environments.
Starting with Citrix Virtual Apps and Desktops 7 2109, all the custom virtual channels are blocked by default.
If you upgrade to this new Citrix version, the existing automation in Citrix via UiPath Remote Runtime stops working.
The UiPath virtual channel must be added to the allow list policy. This can be done by following the instructions here.
The value below must be added to the allow list policy.
UIPCTX,<UiPathRemoteRuntime-Install_Path>\UiPathRemoteRuntime.exe
For example:
UIPCTX,C:\Program Files (x86)\UiPath\RemoteRuntime\UiPathRemoteRuntime.exe
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.
- 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.
When you try to install the UiPath Extension for Citrix, the following error is displayed:
This occurs when the UiPath Extension for Citrix is already installed and an open Citrix App is using it.
Close all your active Citrix App sessions, as described here and then try to install the UiPath Extension for Citrix again.
When you try to install the UiPath Extension for Citrix, the following error is displayed:
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.
Download and install the Citrix Receiver or Citrix Workspace.
Starting with Citrix Workspace App (CWA) for Windows 2206, if no High DPI policy settings are applied, interactive selection and element identification might not work for Citrix Apps when the display DPI scaling is higher than 100%.
This is caused by the following change in Citrix: DPI support changes with Citrix Workspace App for Windows 2206.
