@pur_berger : try to register Atmowin
comand line : AtmowinA.exe /register maybe the registry is broken, and look the rights on this folder.
Good Idea - same behaviour - even when I register the object with the InstallerPath (C:\ProgrammData ...) it doesn't connect. The registry looks fine - the entries are there and they also change when I register it from the root path (C:\Atmo).
The whole point here is - Atmwoin does start and is working in any installation and any path used - as explained it has nothing to do with MP - but MP won't connect.
