Would like to install on another

[W8NEE]

I want to install the program on a 2nd windows 10 that I have, using it as training only, as I will probably never use it with the IC7100. I have attempted to download it, but cannot select it and the downloads accompanying it are nothing that I want. It would be nice as a backup, as they are both Pro 64 bit machines.
Any suggestions?
Thanks John W8NEE
