# Microsoft RDP licensing protocol error

When you connect to a remote workstation, you receive one of the errors below.

```
The remote computer disconnected the session because of an error in the licensing protocol.
Please try connecting to the remote computer again or contact your server administrator.
```

```
The remote session was disconnected because license store creation failed with access denied.
Please run remote desktop client with elevated privileges.
```

### Solution 1

1. Close Remote Desktop Manager.
2. Navigate to **%localappdata%\Devolutions**.
3. Move the **RemoteDesktopManager** folder to your desktop.
4. Restart Remote Desktop Manager.

### Solution 2

In ***File – Settings – Types – RDP*** change the RDP engine to ***RDP (FreeRDP Latest)***.

### Solution 3

Try to check/uncheck the ***NLA*** option located under the ***Connection*** tab in the ***Properties*** of the session.

### Solution 4

In some cases, and sometimes depending on the host OS, the ***CredSSP*** setting may interfere. Change its value in ***Session properties – General – Advanced*** Tab.

### Solution 5

Try to check/uncheck the ***Open Console*** option and see if the error message disappear or is still the same in the ***General*** settings of the ***Properties***.
