# UiPath Remote Runtime blocks Citrix session from being closed

> 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`.

## 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.
