I use this mainly to create DVD videos, the software is rather easy to understand and intuitive. But I could not install it on one of the 2 PCs that I use (1 fixed + 1 laptop). I still do not know if this product can be installed on one PC or if I really have an installation problem. Questioned by me, the NERO platform could not provide me the answer and has not kept its promises to remember (more than 15 days now). When opening the software application each time to record, I tried (not often) without success and therefore this message persists.
