Good Morning,

 

I built my desktop 4 years ago and installed the 32 bit version of Windows (System builder).  I'm thinking of upgrading to the 64 bit of 7 and understand it would be a clean install.  I'm seeing a whole host of price variations for the 64 Bit software.   Some of the cheapest software ($60 versus $120) is what they are calling "for refurbished PC installation". 

 

My question is, why so cheap?  I'm assuming it is because it will use my current license key from the 32 bit installation (treating it like an upgrade)?

Also, since I originally built it with the "32 bit System Builder", is there any restrictions on that original license key which won't allow for the 64 bit installation?

 

Just "kicking the tires" for some gotchas before I take any action....

 

Thanks for the help...

Galad - the COA (Certificate of Authenticity) will work for either 32 or 64-bit, same as Vista. XP had different COAs, specific to 64-bit.

 

All you need is a 64-bit ISO for whatever version you have: Home, Pro etc. If you can't find it for download, buy a Dell/HP/MS 64-bit SP1 DVD on Ebay. Your sticker will work fine, but may require a phone call for activation.

Well...it might help if we had links to vendors listing the various items you are looking at.  It's hard to comment on price variation and just what is being hawked...without seeing whatever it is that you are seeing.

 

IMO, worth a read:  http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_install/windows-7-professional-64-bit-product-key-cannot/ab134133-80d8-4894-b480-e6e9c1eceef0?db=5 .
