Cpu Core 2 Duo: T6670 2.20GHz
I used VirtualBox for years without problems, just wanted to try VMware. But faced with problems before even installing anything.
"View the Guest/Host OS tab on the VMware Compatibility Guide Web site" - this page is not intuitive, overloaded by extra information.
Compare this VirtualBox pages:
https://www.virtualbox.org/wiki/Downloads
https://www.virtualbox.org/manual/ch01.html
A far more intuitive and clear info.
