Thank you very much, Technogeezer. Fortunately I do have an Intel Mac. Unfortunately I do not understand the help texts.
I understand thaat with the Pro-version you have two options; I have installed the free Player-version.
The other option is to export the virtual machine with a vTPM. I have no idea what a vTPM might be & I do not understand the texts on the VMWare internet site. It seems to be some special software. Besides, whenever I start VMWare Fusion (since spring) my MacBook starts to overheat so I have to minimize actions. :-( You have seen my plea for help as you have answered...
So I admit to be at a loss.
Thanks
