If that does not work, try to forget it and install 5.5.1 from a fresh beginning. I did once install 5.0 and 5.5beta in the same machine and it worked fine.

I have used NetBenas 5.5 on WinXP SP2 system with JDK 1.6.0 without setting any "userdir". It works fine. I suggested trying to uninstall it *completely* and install it afresh. It should be a few minutes' work. Check if JAVA_HOME is set to a right place. Thanks
