unity update

i’ve had a trail that I’ve downloaed some time ago, now that I have registered unity I see that my version is 2.0.2, how do I upgrade to newer version? Do i have to download trail again and install it and then register it again? Is there any other procedure?

Just download the latest version. You shouldn’t have to reregister it. The registration should carry over just fine, since it’s tied to the hardware and not to the actual application.

just install the new “trial”
it will automatically realize that you already registered and be 2.1
