Can I run cubase 5.5 and 6 on the same PC

I’d like to try cubase 6 but I’m not sure I want to switch. Is it possible to download the free trial of 6 and try it out while still running 5.5 (I’m a registered user). also, if i decide to purchase 6 after trying it, can I just pay my $$$ and get an activation code or do I have to actually buy the “boxed product.”

thanks in advance,

Yes, and you have to buy the boxed product.

Also, the website says that the trial has all the functions and sounds of the full product but it is NOT true. The Halion Sonic SE content is very sparse in the trial compared to the boxed version.
Sincerely,
