So at some time in the past I had half installed VMware Fusion 10.1.6, but didn't activite the trial period or something? or it reset? I don't know. Perhaps after updating my MacOS to High Sierra.
So I guess I thought it didn't work, but now I have the trial or VMware Fusion 10.1.6 activated (for 1 month). But can I still pay to authorize this version?
I can run the old Windows Machines that I had made using VMware Fusion 6. But yeah, obviously only for the next month.
