Assign it to an OU which contains the RDSH servers or to the computers themselves.   When you do an assignment this way the system will need to be restarted as the app stacks mount on computer/service start up.

Hi Dear Chris

Thank you. I restart the vm but unfortunately it didn't works. I want to check if assigning to OU works for me but it does't show list of OUs.

When you add an assignment and you do a search you will see the OUs come back in the results 

Hi dear Chris and Thank to your time and answers.

I assign app in application tab and even one other tome to RDS server from directory -> computers after setting current marker to appstacks.
