I recently formatted my laptop which came with Vista preinstalled and installed Windows 7 on the primary partition. I've now installed Vista on a different partition, but it won't activate my valid product key. I've looked around on here and have seen similar issues being raised, but I don't have the telephonic activation option (only option I have is online activation). I am located in South Africa.

When I enter my product key from my sticker it says it is not valid, so I must either try to activate online again or buy a different product key. I have reinstalled Vista on the primary partition several times and activated the key without a problem. This is the first time I am installing it on a different partition.

Sounds like you may need to call Microsoft, they may have flagged the key due to so many activations. – cole Nov 3 '12 at 19:17
I've only done it about 4 times before, and according to the help files, I can activate as many times as needed as long as it's on the same hardware. – Cindy Williams-Jayakumar Nov 3 '12 at 19:24

Is it possible you used the wrong Vista media? product keys are tied to version (home, pro etc) and distribution, OEM Retail, MSDN – Moab Nov 3 '12 at 19:43
@Arabella - Follow the directions to manually activate your installation this is your only choice. This involves calling a number and getting the activation approved. – Ramhound Nov 3 '12 at 21:09
