Original Title: Windows XP Activation.
I am reinstalling Windows XP on my Computer. I Used exactly the same media that came with the computer. But When Activation through internet I Got the error message 45090 indicating invalid product-key. I double-check the Product Key, and re-enter it again
but still the problem persists.
I tried through the phone(1-88 number) entering the long number (Installation id) and it is telling me that it is an invalid product number or something like that.
