    Determining Win 7 32 vs. 64 on non-booting system

    Is there any way to be sure that the system I'm trying to repair (probably reinstall) is a 32 or a 64 bit version? Circumstantial evidence:

    • The system only boots into the repair utility, which fails and only mentions "file corruption."
    • I can get to a command prompt and look at any suggested files.
    • Only 3 gigs of memory
    • Toshiba Windows key sticker says "Windows 7 Home Prem OA"
    • Presence of both "Program Files" and "Program Files (x86) folders
    • Attempt to load installer using downloaded 32 bit ISO image disk ended with "wrong version" but 64 bit ISO did not.


    Of course, that last one is probably "proof" but in the puzzling absence of anything that actually says "64 bit" I thought I might want to be sure before blowing away the operating system and discovering that the key doesn't work with the 64 bit installer. It's scary enough that it's a Toshiba OEM system key.

    Thanks for any advice...

    The presence of the two different Program Files folders indicates a 64-bit OS. "Program Files (x86)" will only be present on a 64-bit installation.

    I agree, it looks like a 64 bit installation.
    If you are able to get to a command prompt, have you tried to run a thorough checkdisk with the "R" switch enabled?

    Since you can get to a command prompt you can run this PowerShell Script , scroll to post #10 for the latest version, to find out information about the system including the Bitness of Windows. You will get some errors in the printers section but the info you want plus some other useful data will be displayed.
