Photoshop CS6 and CC hate each other..?

Sooo, I've had CS6 since shortly after it came out, and I didn't even know about CC until I saw the Tek episode mentioning how Adobe failed to keep Photoshop from being pirated yet again. Anyway, I decided to get the trial...

I'm posting here to ask if anyone knows a way to be able to open both CC and CS6 at the same time, because when I try to it always just makes CC or CS6 (whatever one was opened first) topmost, like "hurdur din't you see me here? I is already open..."

It's 2:50 AM where I am, so forgive me if it's really stupidly simple to do.

Is there a way to tell CC to leave the Adobe folders/registry alone? Whitelist maybe?
