Just downloaded the version above and tried to start the app. It asks for an activation key - (which I found!!) but the activation dialogue states that this is on a different machine. In fact it is the same machine.
The older version I used worked fine. When installing the 2.6.2.2R3B version the documentation, the EULA and the wav files all hung up the installer. I moved the older versions, clicked on retry, and the installer continued and finished installing. As I said above, however, the program won't activate.
I still have the 2.6.2.2r3b zip file, so I can easily re-install, but I'd like to know how to do it properly so that I can use the program.
