What to do when Windows claims your product key is inv.

Help! I am installing Windows 7 on a new pc and I have reached the point where it is asking me to enter the product key. After entering the product key, it tells me that the key is invalid. I ordered the product directly from Microsoft so it can not possibly be fake. What do I do ? Send it back and ask for a replacement ?

Try this inbuilt executable, and follow the onscreen steps...

C:\Windows\System32\slui.exe

Hello there,

Did you perform a Clean installation using an Upgrade link?

I get no prompts.

The file is there but no response from the program.

My product key has no O or 0, No S or 5, and no I or 1.

The product is actually an upgrade, but I did not use any links - just did a clean install using the 32 bit product. It looks just like the 64 bit install except it won't accept the key (I ordered two product disks).

Or B & 8.

Shinobi and kegobeer are onto something. Some people cannot activate a clean install done with the upgrade media. There are a couple of tricks to solve that. And they're probably in the thread keg linked to so I won't bother typing it
