This is what my user agreement says:
A. Personal Edition Users (standalone): If you received the personal edition of the Rosetta Stone software (denoted by the A after the version number printed on the front of the application CD-Rom and by *personal Edition* if your printed packing slip) the license granted to you by Fairfield gives you the right to install and execute the Rosetta Stone application software on the hard drive or other storage device of you personal computer for your personal use and the personal use of the members of your household. The application disc may be retained for bakcup. You may not make an additional backup copy of the application disc or language disc. In case either disc us damaged you may return it to Fairfield for a replacement upon your payment of applicable shipping costs. This agreement does not allow the Rosetta Stone Software date software to be executed on more then one computer at a time. You may not make Rosetta Stone Software available over a network where it could dbe used by multiple computers.
B. Online Edition Users: If you have purchased online access to the Rosetta Stone Software (Rosetta Stone Online) the license granted by Fairfield gives you and the members of your household use of Rosetta Stone Online from any workstation matching System Requirements for language learning purposes only. http://www.rosettastone.com/home/support/sysreq/online
So it looks like no for the personal edition but maybe yes for online?
FTR I bought the homeschool version and it does have the A after the version number.
