SAP GUI get client version information

Sorry I am new to SAP but I need to gather information about the installed SAPGui Version and loaded Modules.

I know there is a dialog at saplogon (about-...) where I could export the information to file. That is exactly the result that I need.

Is there any possibility to do this via Command Line (DOS Box) or whatever? Something like saplogon -version >> C:\SAPVerison.txt?

Or are there any registry keys (that I missed yet) where I can find SAPGui version?

Or is there another solution to gather information about version and loaded Modules?

Thanks Frank
