I would like to move Unify to my other drive because I need to free up memory on my c drive. Can I uninstall it in programs and just install it into a new directory?

Is it just a matter of uninstalling Unify in my C:\ directory and moving it to my F: to make more space or do I have to re register it.  I can't seem to locate my registration password.  Thanks.  I am planning on spending some time on it this week.
