When I bought my computer, it came with Windows Vista and a free upgrade to Windows 7 - the 64-bit version.

I took my computer in to repair a while ago and, EVER since, my computer has SAID that only 3 GB of my ram was usable out of 6 GB. I've just found out that the repair shop REINSTALLED windows 7 but the 32-bit version and that I need to get my 64-bit version back. So, I got my "upgrade kit" and tried to reinstall windows 7 but it only lets me do phase 3 of the upgrade process (which is to restore files). It won't let me get my 64-bit version (phases 1 and 2).

How do I get my 64-bit version of windows 7 back? If I have the code, can I get it online somewhere? I have 2 CDs: a Packard Bell Upgrade Media and a Microsoft Windows Upgrade Media. I understand that I might lose data, but I can reinstall all my games. I just need my ram back to be able to play them...What do you mean it "came with Vista"? Did it have Vista installed and then you ran a Windows 7 upgrade disk? If so, I think you will have to get it back to its first condition before you can run the upgrade. Did you get a recovery disk? If not, you may have to order one from the computer maker. Calling their customer service number would be a good first step. Also you may have a valid complaint against the repair shop.




Erias is right.
You must complaint to repair shop.
Since the shop FORMATTED the hard drive to install windows 7 32-bit and erase the partition that contain Windows Vista 64-bit your out of luck, with the CD's or DVD's you have.

The only way to get it back to Windows 7 64-bit, is to order the full restore CD's or DVD's from manufacture , since the ones that come with the computer are just the drivers and programs, but it doesn't include the Operating System.
From there just upgrade to Windows 7 64-bit.

But the easiest way to get it back to Windows 7 64-bit is to get the Full Copy of Windows 7 64-bit from somewhere and just install the drivers and programs you want and your done.I disagree...
The Vista Restore partition (hidden) is probably still on the PC...
He can do the Restore...then re-run the Upgrade pack choosing 64Bit in Setup.
