Hi again Quentin56, I think I have solved the problem permanently on my side. Unfortunately I changed several things at once and can't pinpoint exaxtly what fixed it (😅), but it seemed to be an issue of read/write permissions of the data stored in the ProgramData-folder. My prodecure was: uninstall ctrlX WORKS remove the folders: C:\ProgramData\Rexroth\TrustedStorage C:\ProgramData\Rexroth\ctrlX WORKS C:\ProgramData\Rexroth\WRK-V-0118 C:\ProgramData\Rexroth\Installer\WRK-V-0118 reinstall ctrlX WORKS However, I do believe that only removing the "TrustedStorage"-folder and restarting ctrlX WORKS could fix the issue - I traced another fault to this when not being able to open settings -> licenses without admin rights. If you try this, please get back with an update in this thread 😊 // Daniel
