help activating Win7 HP OEM
Posted on 2011-03-24
We have a laptop that had vista and got a terrible virus.
We reformatted the HDD and installed Win7 Home Premium from a 32-bit install dvd.
At the time of install, we did not enter a product key.
We purchased a Win7 OEM with a RAM upgrade for this laptop a few weeks after the install mentioned above.
We now need to activate the OS because the 30 grace period has expired, but when I run the activation wizard it asks for the product key (which I assumed it would), but when I enter it (the new OEM one) and click next, it comes back with an error and code 0xC004E003.
I've used slmgr /rearm in an elevated command prompt to extend the grace perios, but I really need to get this activated and working again.
Any one got any ideas?
