49	49	You can execute software multiple times, like in different rdp session or if you are logged into your account directly and have a rdp session open. Be aware that not all applications support this. If you receive a notification that your application is already open you need to close it in the other user session so you can reopen it in the wanted session.

79	79	The directory thinclient_drives also need to be acceseable for everyone, which means execution right has to be given in order to unmount this. Please note this, when the home directory is protected. This could be the reason that the error message first occurred.
