All, I am fairly new to Parallels and Macs in general. I bought an Intel based MacPro about 2 months ago together with a retail boxed version of Parallels Desktop for Mac. I found out about the Beta (build 3120) before I installed my retail version and installed the Beta instead. Now I am wondering how the registration process will work. I have a brand new sealed retail box but would like to use the Beta/Release Candidate and of course - as soon as available - the final version that includes all the features of the Beta. Can I register the Beta with a serial# from the retail box and will this also work for the final release? Do I have to uninstall the Beta, install the retail version and reinstall the Beta? Thanks, G.
