Announcement - Citrix v2109 blocks by default all the custom virtual channels

This announcement concerns customers running automation with Citrix environments via the UiPath Remote Runtime and who plan to upgrade to Citrix Virtual Apps and Desktops 7 2109.

What has changed?

Starting with Citrix Virtual Apps and Desktops 7 2109, all the custom virtual channels are blocked by default.
This was announced by Citrix here: Virtual channel allow list now enabled by default | Citrix Blogs.

What is the impact?

If you upgrade to this new Citrix version, the existing automation with Citrix environment via UiPath Remote Runtime will stop working.

What is the solution?

The UiPath virtual channel must be added to the allow list policy. This can be done by following these instructions: Virtual channel allow list policy settings.

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

Hope this helps,
Gheorghe
