mainclass ?jar not found , java.lang.ClassNotFoundException at installation of openkm7.0 on windows

Hello,
thank you for the new 7.0 CE !!!
I tried to install it with the okminstaller on windows. First, I installed the openjkd 11.0.30.
Then, if I started the okminstaller (java -jar okminstaller.jar), the installation stopped with the message "mainclass ?jar not found" , "java.lang.ClassNotFoundException".
I tried the installer with the openjkd version 25 too, but with the same error.

Thanks for your help!
Greetings!
Pitt
