SAP GUI Installation -- Could not connect to host localhost on port 21212. (Firewall open and correct Java installed)

All:

Thank you in advance for the additional help with my install - I appreciate it.

I have successfully installed everything now except for the GUI. When I attempt to do so I receive the following error:

Error while connecting to communication partner - see preceding messages.

Could not connect to host localhost on port 21212.

java.net.ConnectException: Connection refused: connect

java.net.ConnectException: Connection refused: connect

Not sure I understand where this is coming from as not only have I opened the correct ports - I have also opened my firewall to make doubly sure communication is open. Also, I have the correct Java installed.

Any help would be greatly appreciated.

Best,

Khy
