I have windows 7(64) installation setup on a Boot Camp partition on my MacBook Pro 13". I also access this partition through VMware hosted by OS X (snow leopard).

Every time I switch between VMware and Boot Camp windows says that it needs to be re-activated because of hardware or driver changes.

I've tried wmware KB KB 1003426 to no avail. Edo




I am using the most recent VMware and tools.

I've tried "KB 1004917" as well. No Dice.

I'm considering re-installing at this point.

Are you using the latest version of VMware Fusion with the latest VMware tools? – fideli Jan 19 '10 at 2:18
What about this kb article?… – David Kolar Jan 19 '10 at 17:39
Thanks for the suggestions, I actually tried 1004917 quite a while ago with the 2.5(?) version of VMware. Tried again though and it still won't work. :) – Jason Hernandez Jan 19 '10 at 22:27

I fixed this by changing the virtual machine to use two virtual processors, which matches the actual machine.

It seems that 1 vs 2 processors was enough to trip windows activation.

Also try changing the MAC address of the virtual network adapter to match your physical MAC address. – stephenwade Jan 14 '13 at 17:52

If you ring microsoft and advise them of your configuration they will provide you with another activation key for the unactivated setup either boot camp or through vmware.
