Windows 7: Windows 7 Ultimate 64-bit installing 32-bit on my Dell Lattitude E4300

Windows 7 Ultimate 64-bit installing 32-bit on my Dell Lattitude E4300

I just bought a used Dell Latitude E4300 which contains an Intel Core 2 Duo P9400 2.4GHz 64-bit processor and every time I install my copy of Windows 7 Ultimate 64-bit, it installs the 32-bit version.

I have been searching for the last 24 hours online for any issues with Windows 7 64-bit and the Latitude E4300 but cannot find anything helpful for my situation; in fact I have found a couple of sites where people have installed the 64-bit version of Win 7 on thier Latitude and they are having other issues.

I have 8GB of memory in the laptop I would like to be able to utilize, but the system type says it is a 32-bit operating system.

Any help would be greatly appreciated.

The Intel Processor Identifier utility says it is indeed a 64-bit processor so I am unsure why Windows 7 keeps installing the 32-bit version:

That laptop has an Intel Core2Duo SP9400 in it, which is indeed a 64bit CPU. Assuming it's not somehow disabled in the BIOS (and I can't imagine how that could be, especially on a Dell), it would seem you have 32bit installation media. Given that machine released sometime in 2007 or 2008 (Vista-era) and shipped with XP as it's installation default option, it just sounds like somehow you have non-Dell installation media, and it's a 32bit install.

Thanks for the reply Culberti.

I have a Dell Operating System Reinstallation DVD which is labeled Windows (R) 7 Ultimate 64-Bit. Is there a way to tell whether it truly is what it says it is? Is there an MD5 hash for the 64-bit versus the 32-bit I can check against a file or files on the DVD? I am at a loss. I thought I had all my ducks in a row when I purchased the laptop and dvd. The laptop came with Vista Business 32-bit installed but I wanted 64-bit Win 7 to take advantage of the extra ram so I bought it separately.

Have you ever installed YOUR COPY on anything else ? That`s really the only way to know for sure. Just download and burn the Iso as Greg says.

You do know your gonna need a key. The key on your laptop will be for Vista, that is if you can even read it.

Did Dell sell you a Windows 7 Reinstallation disk for a Vista computer?

Is this an Upgrade version copy of Windows 7?

Is there a Product Key with it?

The thing is, Dell "reinstallation" DVDs are just Microsoft DVDs in most cases - they don't even have token activation or drivers inside. If someone is getting a 32bit install from a Dell reinstall DVD, then it's probably just mislabeled (unless it's a dual-layer DVD, it's only going to contain one Windows 7 architecture - given it's specifically labeled 64bit, it likely only has one).

@RPSuede, can you post a screenshot showing Windows Explorer with your C:\ drive open? I am specifically interested in the folders that exist on your C:\ drive after installing with that Dell DVD. Otherwise, do what gregrocker suggests and download the official 64bit ISO, make sure your checksums match the ISO you downloaded, and install from that.

I beg to differ.

Just about a month or two back DELL India sent me the OEM Reinstall Disk (not the Recovery Disk) -Windows 7 Home Premium 64 bit - for my DELL Inspiron 1120 (M 101Z) netbook.

With a clean install it auto-activated confirming that it has the token activation built-in.( I have checked the OEM-SLP key too after the clean install. Tallies with what I had backed up earlier.) It was also heavy at 5.74 GB. The reason as I found out was it is a multilanguage pack.
