Move Mathcad Prime+Mathcad 15 to a new PC I have a Mathcad Prime license, with Mathcad 15 software associated.I successfully moved Mathcad Prime to another PC, thanks to the fact that I got from PTC the new license and I have the source and installation software on a CD.On the other side, I couldn't install Mathcad 15, because in the past I downloaded it on the old PC from PTC web site, but now I cannot manage how to do this.Please, help me in installing Mathcad 15 on my new PC.Thank you.Sarah Bollanti
