How to runn 1.5 and 1.6 on one machine

I am working at a studio that is using 2 versions of SBPro. My current production is using 1.6. All other productions 1.5. I would like to be able to switch back and forth on the versions on my home machines, depending on what I’m dealing with. Obviously I cant do a 1.5 work on my 1.6 machine without corrupting those files, however I don’t want to have to uninstall reinstall everytime.I have a tablet pc and a Mac tower.How can I run 2 versions on one machine?

For this kind of a specialised case, please email and they can help you with your setup.~LillyToon Boom Support
