Windows 7: Moving from Win7 32bit to x64

Thankfully Microsoft have schemes like this to support UK students, (dunno if there are similar deals for US Students) It would still be annoying to buy software I couldn't use though

Known blogger Ed Bott says it happens a bit differnt than I thought but still agrees that its legit to do.
Finally, some answers to Windows 7 upgrade questions | Ed Bott’s Microsoft Report | ZDNet.com

How about 32-bit to 64-bit upgrades?
You canít run the 64-bit installer from an existing 32-bit Windows installation (or vice-versa). Hereís how you have to do it instead. Start your computer using the 64-bit installation media. When prompted, choose the Custom installation option:

Youíll be warned that your current installation of Windows will be moved to Windows.old. Thatís fine. Continue with the installation, entering your product key when prompted. Because a previous Windows installation was on your system drive (and is now located in Windows.old), you should be able to activate.

Many thanks for that myzr7
So I'm guessing the confusingly worded 'not possible to do a clean install' in regards to the European releases just means you can't install it on a fresh hard drive and do the 'double install' trick.

But I will still be able to re-format and remove the 32bit install the 64bit version in it's place using custom install. Seeing as if Microsoft removed this ability completely it would mean less people upgrading due to being in situations such as myself.

Many thanks again.

If you want to change from 32 bit to 64 bit then why not use the same license you already purchased?

All licenses are good for either 32 bit OR 64 bit, just not both at the same time.

Find a 64 bit installer for your version (installers contain all versions but some are hidden), boot install it over your 32 bit OS and it should accept the key.

If you have questions whether this is the case in your country, contact tech support for the Win7 your purchased which is always included in the price.

You can achieve the clean install from boot required for switching to 64 bit and still use an Upgrade version because the DVD scans the HD for installed OS to allow use of Upgrade version key, before you format.

If the disc is like the ordinary US version, you CAN do a clean install on a brand new hard drive, regardless of any warnings. If I had to guess, I'd guess that disc will work the same way--but that is just a guess.

The only fine print is that the EULA requires that you own a qualifying operating system.

what i have read up on this, it is not possible to upgrade from 32 to 64.
the only option is a clean install.
the folowing is not to say that legally you are alowed to do this, you should check this up yourself.
there is an option of borrowing someone else's 32 installation disc, and making a clean installation. without putting in a serial #, then "upgrading" with your disc. it shpuld work.
another option is to do a clean install with your disc, and then again install with the same disc, calling it a upgradenever tried it myself, but they say it works.
the firs is prefered, mostly you save yourself a lot of time.

you can partition first in case your worried if it really works.
the first way definitely works.

It is not possible to in-place Upgrade from 32- to 64-bit, but the Upgrade version can be used to clean install. All you need under the EULA is qualifying XP/Vista on hand which is not used while Upgrade is used.

If you boot from the Win7 64 bit installer to clean install, it will scan the HD to see the 32 bit OS and allow the Upgrade key. It only needs to see an OS. You can then delete and repartition as you wish, format and install..

Lil' Dom, Thanks for sharing your real world experience. This should give the OP the confidence to forge ahead with his upgrade/clean/custom install.

No problem
I didn't know there could be problems with the custom install with a repair disc, i was aware if the 32-bit to 64-bit dangers, but checked the Intel website to ensure the processor was 64-bit compatible, and it was.
