the 3 methods didn’t work for me but i found a simpler work around.

I actually tried all three methods but none worked, BUT I found a solution:
Go to Local Disk (C:)UsersYOUR USERNAME.VirtualboxVirtualbox.xml and open it with notepad.
Now open command prompt (don’t close that notepad I told you to open) and type in: wmic path win32_computersystemproduct get uuid
you will see a 36 character format, copy it, now open that notepad and find the place where it has soo many zeros, select them all and replace them with your UUID (the thing that you just copied) and save the notepad, now open virtual machine, ****this is a rare case for me.
