This is very similar to this unresolved question, but I would very much like to install two versions of the same application in OSX. How can you do this and what is the best way to do it?
Specifically, I currently have Parallels 5 installed on my laptop virtualizing, among other things, Ubuntu 10.04. I tried to install Ubuntu 12.04 this morning and there was a problem installing it in the old version of Parallels. As a work around, I was wondering if I can install Parallels 8 (alongside my existing version of Parallels) in which I can virtualize Ubuntu 12.04. Any suggestions here?
Update: I suppose I could use another virtual machine (e.g. VMWare) to host my second version of Ubuntu. I prefer the Parallels framework as a colleague of mine has been extremely dissatisfied with his VMWare experiment. I further suppose that I could risk updating Parallels but I am (unnecessarily?) concerned that the upgrade might affect my virtual machines.
