Windows 7 - Windows 7 Key only works with 32 bit, not 64 bit?

During installation using 64 bit dvd it says the product key isn't valid, but it works fine on 32 bit dvd.

Any ideas?

Thanks very much.

can you tell us where you got the dvd (download, or retail) and the keys. and what version (ulti, pro, home) it is

It's a retail version of Windows 7 Home Premium Upgrade.

Thanks

I've give Microsoft a call on that one. That same key should work for either version.

These keys can only be used once.
If you already tried the key in 32-bit then it'll show on MSFT computer as used, so phone them. When you try to activate it should give you that option.

I tried the 64 bit version first. Go figure.

That's a bind. See here: Activate Windows 7 by Phone

I got the same issue. Upgraded from XP 32bit, but 64bit DVD wouldn't run in Windows. Booted from DVD and did a custom clean install, everything installed fine, got to the Install Key screen and was told key was invalid. Punched it in several times, same result. MS Techs told me bc it was 10/21 and that's why the key wasn't working, tried again on 10/22 same result. Can't get to the desktop until this key is entered. I'm sending it back and going to go buy another copy at BB. Hopefully it will work unless someone has some other idea?

So I installed the 32 bit..activated it. Then I decided to try the 64 bit again and it worked! Strange.

Alot of people with the "upgrade" version of Windows 7 seem to be having this problem. Not heard of anyone with the full version reporting this issue...
Ex-brit mentioned you can only use a key once? I REALLY hope that's not true!
