Are you launching your tools as a different user account? The PSExec path is stored per user, so Configure Recast RCT would need to be launched as the user that the ConfigMgr console is launched as. It might also be worth checking that the user running the console has permissions to the path that PSExec is stored in.
I am running the console as a user with rights to the local psexec path and rights to connect to connect to the remote machine (where that user is part of the admin group of the remote client).
If I run psexec via the command console as the same user I can connect.
Yesterday i tried with the old version (3.2.6962.38904).
Today i upgrade to the newest one (3.2.7026.33608).
The newest version fixed the problem thank you very much
Next i read the release notes in more detail.
Maybe your account isn’t admin on the device you want connect? I got the same message, but if i use a account which is in the admin group the connection works. In my case i have to accounts. So i open the sccm console as different user and use my admin account.
