SQL Developer

I installed Oracle 11g on Windows 8, and am having problems with SQL developer starting. I have tried to debug but not a clue what I am looking for. I really could use some help. It is a 64 bit installation - and seems to be OK as I can connect to the DB in SQL plus. Thanks a lot!

From a self-help perspective, did the following after looking at some threads:

Ran sqldeveloper.exe and the output I got is:
