I was thinking that I could just install Windows 10 32bit and run the program from a virtual machine
try it and see - I have some software that requires this; in fact I had some software that fell over after 4 weeks or so when the trial ended but I could start again from scratch, it depends how the activation works; and, thankfully I no longer need this now at all, so I'm spared the hastle

It depends how much you need the program does it not ?

If Corel cannot help I don't see what else you can do...

EDIT - should add, for the avoidance of doubt, that I had purchased said software, but the activation no longer worked
