Cannot log into GUI, status 526

Hi,

 I have the same issue as in this post: https://vox.veritas.com/t5/NetBackup/Cannot-log-into-GUI-status-526/m-p/774687
 but in windows 7.

So i`ve installed NB java 7.6.1 then the patch to 7.6.1.2. and ports 1556 and 13724 are allowed in my local firewall.

This inst is made on a laptop, not on netbackup server directly.

I have the same issues on another laptop.

What is wrong here? I have installed also remote console and it works, also the nb client, and still java is not working.
