Can I install on second computer?

I have two mac's that I want to install parallels on. I have purchased one copy, am I allowed to install it on both of my computers??

 

I have both a Mac desktop and laptop and have a single copy of Parallels for Mac. I am interested in this as well since I work between both computers. Some of my other software allows me to make a copy for both my desktop and laptop.

 

I finally got ahold of a person at parallels, the one copy that we bought is only good for one computer. I had to buy another copy for my second computer

 

ewwww... not a good answer for me in the current economy... oh, well... only on my laptop!
