Hello, in ctrlX PLC Engineering (WRK-V-0118.2) the VisualElemRepository Assembly is installed in Version=4.2.0.0. Can you try to clean the PluginCache files (C:\ProgramData\AP\PlugInCaches\StudioPlc-*.cache)? Did this solve your problem? If not, can you provide some more information when the crash dialog appears, did you do a clean new installation or did you install additional packages. How did you start the ctrlX PLC Engineering (Shortcut or via ctlrX WORKS?) Regards, Oliver
