Hello,
I got the connection working now and can open the developer on my local machine (ty to jasmin)
What you are saying about the GUI also seems to be true. I downloaded 'abap sap gui for windows' but when i try to install i get following error screen:
I'm 100% sure i got the right java environment so how can i fix the install sap gui 7.20 problem?
Thank you all for effort putting into this, it's appreciated.
