Neither Amazon nor in Nero is made transparent, that you can not operate on multiple PCs own this product. I installed the program on my desktop, then on my laptop that I wanted to take on holiday to get settled in the program.
After I had (about 300 MB) spent a longer time with installation and download and install updates on your notebook, appears to me that I can not use the program because it is already installed on the other personal computer. It is also said not directly, that this does not go, but asked if there is another installation. After that you will be pointed to a link with a purchase option (upgrade), but where there is nothing to buy, since I already have had the most expensive version.
I would not have said suspected because I never had this problem with my old Nero versions, which I have received over bundles.
Too bad!
