Photo editing software?

Only gripe I have about "Elements" is that I bought a copy and when I first STARTED to install it the very first thing they demand (I found no workaround) is to register and your email

What pisses me off about this sort of thing, Let's say you are a pro in the field, maybe broke your computer, and need to reinstall, or whatever. You are somewhere there is no internet. Lord I hate this stuff!!
