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.
