two versions of PS at the same time?

Hi! I've got myself version 7.0 of Photoshop. But I want to have my old version of Photoshop, version 6.0, installed too, at the same time (and in the same Operating system of course). Is this possible?

Both of my versions are the full versions, not the "upgrade" versions. My version 7.0 is in my home language, swedish, and my version 6.0 is in english.

Hope you have an answer :-)

Yea, that's no problem at all. When I was writing some of the tutorials, I had version 5.0, 5.5, and 6.0 running at the same time, just to check what some of the differences were. No problem- as long as your machine has enough RAM for the software. I've got a lot of friends who prefer older versions. Even though they upgrade, and use some new features, they prefer whatever work environment they got used to.
