I dont see whats wrong with that. I install Corel ( and Wilcom) onto my work PC and my laptop and use them at separate times. If I had a separate PC for a printer or cutter in another room then I would be annoyed but I would then network it.
After all, you have to buy a separate operating system software for each computer so we should be happy that Corel allows us to use their software on two computers at the same cost.
