Deltav 13Workstation download problem

Hello!
I am an EE student working for the first time on a project using DeltaV 13. 
Whenever I try to download the workstation, I get this error message popping up:

"AB-20180410 DO NOT DOWNLOAD THIS WORKSTATION.

Doing so will cause this workstation to become un-configured.

This workstation is not running a Remote Client operating system or the Terminal Service is not installed. Delete the Remote Client Sessions on this workstation, uncheck the Enable Remote Client Functionality on this workstation's property dialog and read the DeltaV Remote Client Overview section in DeltaV Books Online."

 I also had many other problems like commissioning a controller or opening the DeltaV Operate Configure, but I think most of them are caused by the first problem. Can anyone tell me how to fix it?

Thanks :)
