Unless you ordered OEM, you're getting both versions in the box anyway.

I'm unsure why you would revert to 32bit if you've been running 64bit Vista.

 

He didn't "revert" to 32-bit. He just "forgot" to order 64-bit, accidentally.

 

Oops, miss-read, sorry . My initial statement stands though. Unless he has ordered OEM, he's getting both versions so it won't matter .

 

If you can get hold of a 64-bit disc you should be able to use your 32-bit key with it.

 

this is correct. the license-keys are architecture inspecific.

 

Im pretty sure both versions are on the disk.

 

Trying to sound clever doesn't work when you use a word that doesn't exist such as "inspecific."

 

Thats only the full retail that come with both 32-64bit versions, the upgrade disks are either/or, not both.

 

I apologise, I missed a hyphen. Do you want a cookie now?

 

OMG the internet police are here




thank god for them, for protecting us users

 

i think the mistake was that you should have used unspecific.

are there noticable differences between 32 and 64 bit?

 

Memory limitation of 4GB.

 

Also if you're gonna choose the upgrade option you can only do 32->32 or 64->64, you can't do 64->32. That'll require a fresh install.

 

Could you not just cancel your order and re order 64 bit? Or failing that you could download a retail 64bit disk from somewhere and use your 32 bit key to activate it. Hell I don't mind sending you my 64 bit copy if you cover the postage

 

Of course it's not too late. It's a preorder. It's not too late even if it got shipped as you can fall back on the distance selling regulations.
