GUI setup error: Could not connect to host localhost on port 21212



I setup the trial of SAP 7.02 on Windows 10 and installation had been without problems reported.

When I check SAPMMC everything seems to run but when I like to setup the GUI I get an error:

Error while connecting to communication partner - see preceeding messages.

Could not connect to host localhost on port 21212. Connection refused: connect Connection refused: connect

When I check "netstat -an" there seems nothing to listen for port 21212.

Aslo the start.htm point to an URL:


If I call this URL I get an error 403 Service can not be reached.

I'm using Windows 10 with 4GB and JAVA JRE 1.8.

Maybe JAVA version is not compatible with SAP 7.02 ?

Can you help please?

Thank you in advance!
