Minimserver install fails: unable to access shared folder

[z624391]

During (clean) installation of Minimserver App with TS-473 (with Java or without Java), the procedure breaks/stops with the message "unable to access shared folder". The installation is ending with a new Minimserver folder (on the assigned volume) which is completely empty, security settings where alright. Therefore the log files where also not available.
Is it possible to set a trace to see what is happening? We can also have a Webex session if you want.
