I’ve seen this error twice this week on two Windows Servers with the Essentials role installed. One was 2012 R2 Server and the other was 2016 Server. When you run the Dashboard app from a client computer, you get the error below
Windows cannot stat the RemoteApp program.
The following RemoteApp program is not in the list of authorized programs:
For assistance contact your system administrator.
For some reason yet to be determined, we found that a registry key was set incorrectly. Thanks to Susan Bradley for your help here.
To fix it,
- Run Regedit on the Essentials Server itself
- Find the location HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server\TSAppAllowList
- Find the key “fDisabledAllowList”
- It will be set to “0”.
- Change to “1”.
No reboot is needed for this to take effect, just try accessing the dashboard again from the client computer and it will work fine.
