You are not allowed to start this external app

[ILA]

I tried the same and it's working for me - just to be sure we configured the same here are my steps…

Create Ext.App. -  notepad.exe - set permission "Everything allowed for test group"

Create Connection - set protocol to Ext.App. - add role "Ext.App." - set under Ext. App. "Notepad.exe" to be started - set permission on the connection "Read allowed for test group"

Logon with user from "TestGroup" - goto created connection and double click - Notepad.exe is starting...

Hi

This does work but when I create a new connection and set the ext. app as the protocol, this new connection does not work for normal users and gives the error "You are not allowed to start this external app"

I finally found why this happens, i needed to go to Ext.App properties and set my new Ext.App as the connection in Default Values. Now it works for all users.

Thanks, you put me on the right path.
