Look Serif, this is a very anti-consumer move you've made here. I do not enjoy being locked out of anything on the hard drive I own, for any reason. And frankly, I don't trust you (or Microsoft) enough to keep your stuff on my hard drive where I can't scan it for malware or simply inspect. If you treat your customers as enemies, do not be surprised when your customers treat you back the same way.
I will not be purchasing V2. Not because of spite mind you, it's just that an app packaged this way has no hope of ever working on Linux, where I spend more and more time.
Which is sad, because being quite satisfied overall with V1, I had already taken out my credit card to make the purchase when I saw V2 launched. Thank goodness I decided to take a short detour to the forums to see what's what.
I hope you reverse this awful decision, and then we can do business.

Take a look at this video for more details on doing this.
