Windows 7: how to upgrade from 32bit to 64bit

21 Aug 2010   #11

Windows 7 Pro X64 SP1

I suppose it's against the rules to post links here, but there are links to legitimate versions of some of the .iso files online. They are from online sites that legitimately sell the OS. (They are of little value without a license key.) A few seconds of web searching ought to find them. (The DigitalRiver links appear to still be live.)

I've never tried the conversion to a generic installer (through removal of ei.cfg). It may be easier if you do it from a USB key:

Use a USB Key to Install Windows 7—Even on a Netbook

You wouldn't need a proper .iso utility to do that; 7Zip (freeware, open source) can extract an .iso.

Good luck.

Of course, the easiest way would be to contact the seller and have them supply the disk that they should have provided in the first place. If the Windows Certificate of Authenticity says 64 bit, they should give you no argument.
