Hi Open,
this message shows, tht the Device description for the simulation device is not available. This can be based on some installation failures or the missing file in your installation.
Are there any other failures shown while using ctrlX PLC Engineering? You can zip the installation Log files (see path C:\ProgramData\Rexroth\PackageManager\Logs) and attach them here to have a look on it.
Have you downloaded the installation from our collaboration room? In any case I recommend to you to download the recent version 1.20.5 and install it and try it again. If this is not possible, please give us feedback!
