Xibo problem when runing in RDP

Hello,
We want to setup Xibo in MIcrosoft RDP. We have many users and they log to One server using RDP. they have second screen and We want to display some advertisment on it, when they working (We have large network of drugstores).
So I tried everything and Setup xibo for each user, but the problem is, that Xibo Clients killing itself during and watchtog trying to run it again. First I thought, that watchdog was the reason, but without watchdog clients is killing itself anyway.
please help with this issue.

My apologies for any misunderstanding but can you confirm again how your setup works?

Am I right in thinking that your Users log into the server using RDP and whilst using RDP, you would like the Xibo Player, which is installed on that server, to show advertisements to the User?

Many Thanks…

Thank you for answer.
I’ll try to give more details:
In Drugstore There is Computers and each Computer have Second Screen, which we use for displaying information what customer is buying, product name, price etc. We want to display advertisments on this screens, when there are no activity.
Computers using special software and Connecting to Central Server using RDP.
So our task is, to run xibo client for each RDP User on One Server.
Today I tried many different configurations and came to solution, which I think will work, but not sure yet.
I copy Xibo Client folder to each user documents folder, renamed xiboclient.exe for each one and put on startup .exe file shortcut.
Then I changed every client key to unique value and from server, for each user changed server port in display profile.

I hope this configuration will work, but it is very difficult to setup, because we have approx. 500 users and setup will be very time consuming:)

Hope you give better and proper soluiton.
