UiPath Remote Runtime blocks Citrix session from being closed

Description

At installation time, UiPathRemoteRuntime.msi registers UiPath executables for Citrix auto clean-up by adding them under the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI.

Value Name: LogoffCheckSysModules

Type: REG_SZ

String: UiPathRemoteRuntime.exe,FuncServer_x86.exe,FuncServer_x64.exe,UiPathRemote.exe

This is an example of how the LogoffCheckSysModules registry key should be configured:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI]
"NotifyEvent"="WfshellTwiNotify"
"DllName"="Seamls20.dll"
"LogoffCheckSysModules"="CitrixFiles.exe,UiPathRemoteRuntime.exe,FuncServer_x86.exe,FuncServer_x64.exe,UiPathRemote.exe"

The effect of removing the registry changes is that Citrix sessions are not cleaned up when all opened applications have been closed, because the UiPath executables are still running.

Solution

If you make any additional changes to the LogoffCheckSysModules registry key after installing UiPath Remote Runtime, make sure you add the UiPath executables (UiPathRemoteRuntime.exe,FuncServer_x86.exe,FuncServer_x64.exe,UiPathRemote.exe) to the list, to ensure Citrix remote sessions are closed correctly.
