If you're banking on Win 10 for the long haul and not willing to buy a 3rd machine of upgrade the 2 you have, then it sounds like either need to get the VM solution working (some folks here have reported this to be viable), or bite the bullet and switch to other s/w.
The "hack" to try and run it on Win 10 has been suggested but no one has posted here about getting it work, it's probably the worst option as you'd be invalidating support from Intuit but up to you.
