How do I not turn on Unity Pro 30 day trial?

I just downloaded Unity, but haven’t turned it on yet.

I’m just dipping my toe into Unity, so its basic functionality will be fine to start. There is no way I would get much use out of the Pro version in the next 30 days. So while I am interested in trying it at some time in the future, I have no interest in it now. Starting the Pro trial would be a waste. I just want to start using plain old Unity without starting the clock on the Pro trial.

Any ideas on how to just use Unity and not the Pro trial?

If you do nothing, you will be using the indie version. You need to specifically activate the pro trial- so you can do that when it will be most useful to you, not now.
