With the command line parameter
-reg 'Element name' , the Startup Tool
registers the version with the name Element
Registration process is shown in the output window (like the registration via the user interface). After that, the Tool is ended.
If the tool is already running, it will be put into the foreground and nothing will be registered.
zenon_Startup.exe -reg 'version 6.22' registers version 6.22. Provided that there is an entry with this name in the Startup Tool.
