I used to be able to run Parallels on my home desktop machine as well as on my laptop when I was travelling. This functionality has now been removed. I have been a user of Parallels since 2007. It is very disappointing to have had this changed. I upgraded from version 3 to version 4, 5, 6, 7, 8, 9, 10, 11, and 12. I don't believe I'll be able to continue to be a customer, however.
