Uninstall any version of Java that is running on your system
Reboot your machine
Install JDK 7 update 17 (32 bits)
I had the JDK 7u17 installer in my system. I don't know if it can still be downloaded from the Oracle site.
Yeah, it works! Last Java update crashes Nokia SDK emulator because when we try to open it, Java creates two instances of the emulator. That's why it says that we need to enter other rmi registry port.
