I'm right now in the test period and interested in buying a full license.
One question prevents me actually:

99% I will use the software on my Win10 laptop.
Very rarely, for example when an USB drive can't manage and I need to rip with a normal full drive, I would like to use the software on my desktop PC (Win10).

As a family pack is overkill for this and therefore way to expensive:
Is it allowed and possible to install it on two machines as long as I do not use more than one at a time? Important here: I assume this is without problem in case I uninstall and install each time, but this would be a show stopper for me, as it makes too much afford for ripping one or two problem discs each couple of weeks or months....

So: purchase a single license, install it permanently two machines and use just one instance at a time is possible?
