Is it possible to “upgrade” from a 32bit to a 64bit installation?


Answer #: 1

You will find a clean install a lot less hassle than any other unusual, obscure, unsupported method.

Your suggest of partitioning the config files, home directories, etc is probably the best idea, and it is possible to install the same packages on a clean install as on another install.

On the other hand, what you requested is possible, there is a little guide for Debian based systems but remember “this really is for professional-level sysadmins” and “this procedure is, in every possible respect, a bad idea. If it eats your firstborn, please don’t come crying to me”… (so good luck)

Answer #: 2

This might be a much more reasonable thing to do once the multiarch spec is implemented. — currently postponed to 11.04, but keep in mind it’s been postponed for about 6 releases now. That said, actual progress was made in 10.10, so maybe it’ll happen this time.

Until then, don’t bother. Backup your...

Nowadays 64-bit operating systems are very widespread. But 32-bit OS are still present on the market, in quite obvious quantities. A lot of modern program tools are developed to be run only in 64-bit mode, because the maintenance of both 32 and 64 bit operating systems requires additional expenses.

For the users of 32-bit OS, it is sometimes necessary to use software designed only for 64-bit OS.
So what shall the user do if he/she is not ready to stop using the 32-bit OS as the main working system?

There are certain peculiarities in different operation systems, related to the 64-bit applications launch in the 32-bit environment. Firstly, starting 64-bit applications in the 32-bit environment you lose the benefit of using more RAM. Also, to support 64-bit applications your processor should have a 64-bit architecture. Let's take a look at some of the most popular OS.

In the Mac OS X the core is a hybrid one. It allows the running of any application...

Is it also possible to use the Rescue and Recovery for Windows 7 download to go from 32 bit to 64 bit? Has anyone tried this?

I assume that you are saying that you want to back up your personal files with the Win7 32bit version and restore it back with the 64bit version, right? however, it does NOT address someone who purchased a special MS produced Win7 Home to Win7 Pro or better upgrade, which I understand has a UPGRADE option not available normally. That MIGHT migrate the same way Win7 was supposed to migrate from Vista 32 to Win7 64bit. Lenovo however did not recommend it since the ThinkV. utilities are not compatible so they suggested custom install and then the thin client that downloads/installs the basic Think utilities.

As for 32bit Lenovo Rescue files being compatible with 64bit Lenovo Rescue files, that is a specific question someone...

If your PC has a 32-bit version of Windows 10, then you're missing out on some productivity advantages. Use this guide to switch to the 64-bit version.

Microsoft offers Windows 10 as a free upgrade for computers running a genuine copy of Windows 7 or Windows 8.1. Also, similar to previous releases, the operating system is available on different editions and two versions: 32-bit and 64-bit.

While upgrading from Windows 10 Home to Windows 10 Pro is not free, what many people are unfamiliar with is that Microsoft won't ask for more money to upgrade from a 32-bit to a 64-bit version.

However, the upgrade path only allows moving from a qualifying version to its equivalent edition on the same architecture. This limit means that if your PC is running a 32-bit version of Windows 8.1, after the upgrade you'll be stuck with the 32-bit version of Windows 10 -- even if your computer's processor can handle the 64-bit version. The only solution is to make a clean...

I'm sorry to say that an upgrade from 32-bit to 64-bit Ubuntu operating system is very difficult to accomplish successfully. A manual migration would be a much simpler way of moving to 64-bit.

If you attempted to upgrade the system manually (as there is no way to do it automatically), it would first have to uninstall every package on the system with all dependencies, and this would include your kernel, grub and pretty much everything else on the system. The chances of having everything reinstalled exactly the way you had it before in 32-bit mode are very remote, and you might even find that some things get corrupted or deleted on the way.

Your only path in this situation would be to back up your /home directories, your /etc directory, anything in your /usr/local directories and all other files and directories you want to keep. You might want to check out etckeeper (find our more: etckeeper) for a good way to back up your /etc directory to a source control repository...

Ever since Microsoft officially announced the launch date for its upcoming Windows 10 operating system and started allowing users of previous Windows versions to register for the free upgrade, we have been getting tens of emails every day with variety of questions.

We have already let you know that it’s possible to upgrade to Windows 10 without losing data and keeping most of installed programs. We have also told you that you can perform a clean install of Windows 10 once you successfully upgrade from Windows 7/8.1 to Windows 10.

Can I upgrade from 32-bit Windows 7/8.1 to 64-bit Windows 10?

A PC user running Windows 7 wants to know if it’s possible to upgrade from Windows 7 32-bit installation to Windows 10 64-bit. In other words, the user wants to if it’s possible to upgrade from x86 flavor of Windows 7/8.1 to x64 flavor of Windows 10.

The answer is NO. One can’t perform an in-place or direct upgrade from 32-bit Windows 7/Windows 8.1 to 64-bit...

Microsoft gives you the 32-bit version of Windows 10 if you upgrade from the 32-bit version of Windows 7 or 8.1. But you can switch to the 64-bit version, assuming your hardware supports it.

If you had a 32-bit versions of Windows 7 or 8.1 installed on your PC and upgraded to Windows 10, Microsoft gave you the 32-bit version of Windows 10.

Is Your PC 64-bit Capable?

First thing’s first, you’ll need to confirm whether the CPU in your computer is 64-bit capable. To do so, open the Settings app from your Start menu, select System, and select About. Look to the right of “System type.”

If you see “32-bit operating system, x64-based processor,” this means you’re using a 32-bit version of Windows 10 but your CPU can run a 64-bit version. If it doesn’t say you have an x64-based processor, you have a 32-bit CPU and can’t upgrade to the 64-bit version.

In the FAQ , in relation to upgrading from x32 bit to x64 bit, it says the following ;

Yes, but you can't do this using Upgrade Assistant. If your PC has a 64-bit capable processor (CPU) but is currently running a 32-bit version of Windows, you can install a 64-bit version of Windows 8, but you'll need to buy Windows 8 as a DVD.

You also won't be able to keep any files, settings, or apps when you upgrade from a 32-bit to a 64-bit version.


The thing I dont understand is the part about buying Windows 8 as a DVD. Previously it's been possible to upgrade from x32 to x64 via a normal upgrade but it has been a clean installation, not an in place upgrade.

And also does it mean that you have to buy a full version as a DVD ? The different upgrade paths confuses me a...

When you received your Windows 10 upgrade, Microsoft will have automatically provided you a like-for-like 32-bit operating system. But if you’d like to upgrade to the 64-bit version of Windows 10, you can – provided your hardware supports it.

Why upgrade? The 64-bit version enables you to use more than 3.75 GB of RAM, providing you with a faster Windows 10 experience. Moreover, 64-bit Windows 10 requires NX support as standard, gifting your processor another layer of protection from malicious attention. For more information please see the Hardware Specification section below.

Upgrading to 64-bit Windows 10 can be a quick process, depending on your existing system settings and system hardware, and I’m here to guide you from one to the other.

You need to be very careful when you want to upgrade from a 32-bit version of Windows to a 64-bit version of Windows 8. Microsoft, for whatever reason, decided to make things complicated. If you run the Upgrade Advisor to buy a copy of Windows 8 online, you will always get the version of Windows 8 that is corresponding to the currently installed version of the operating system. So, if you are running the Upgrade Assistant on a 32-bit version you will end up with a 32-bit Windows 8 version, while running it on a 64-bit version of Windows will result in a 64-bit version of Windows 8.

That's not a problem if you do not want to switch from 32-bit to 64-bit during the upgrade, but if you do, you will notice that you can't do that at all. If you are unlucky, you will notice once the system is up and running after the installation.

I just tried the solution suggested above by Nick (Oct 19'13): Using the Ubuntu 64-bit Live CD to do a 64-bit reinstall.
I used the Ubuntu 14.04.4 Live CD. But if the first option is indeed called a "reinstall", it more precisely appears as:

Erase Ubuntu 14.04.4 LTS and reinstall Warning: This will delete all your Ubuntu 14.04 programs, documents, photos, music, and all other files.

The two other options offered by the installer on the Live CD are:

Install alongside (dual boot option) Erase disk and install Ubuntu

To be real sure, I tried with a test disk, and indeed, the first thing the "reinstall" option does is to reformat the existing ext4 partition. No luck.
So I'm afraid the "upgrade in-place to 64-bit" solution Nick suggested doesn't exist anymore in 14.04.
And BTW, Canonical, I hardly see the point for the installer having both the so-called "reinstall" option and the "Erase disk and install" one. Both seem to do about the same...

I'd like to clean install a 64bit version of Windows 8 from an ISO file on a HP Pavilion dm1 notebook without disc-drive running Windows 7 32bit.

The setup.exe from the ISO file cannot be run on the 32bit OS. For the same reason it doesn't seem to be possible to create a bootable SD-card with the Windows 8 installation files using, for instance, Microsoft's 'Windows 7 USB DVD Download Tool' or the BOOTSECT.EXE command on the 32bit machine.

I managed to create a bootable SD-card from the ISO file on a 64bit computer. However, I couldn't bring the 32bit Pavilion to boot from it.

I tried creating a VHD on an external hard drive following this guide but ended up having Windows 8 installed on the external drive itself instead of being able to run the installation process from the drive at boot.

How can I clean install Windows 8 64bit from the SD-card or the external drive on a 32bit notebook computer?

Our clients install our product on different environments. Some of them have 32bit server OS others have pure 64bit environments. Due to the lack of a 64bit version of a driver we use we have to run certain tools in 32bit mode. But since we do not want to have multiple versions of our product we had to find a possibility to force a .NET (command line) tool to run as a 32bit process on a 64bit OS (e.g. Windows Server 2003/2008).


Set the platform target

The simplest solution is to set the Platform Target to be x86 on the project properties (build register).

This will cause the compiler to set the 32Bit flag in the CLR header of the corresponding assembly. Every time we run this application no matter on what type of OS it will execute as a 32bit process. But this solution although simple and straight forward was not a viable solution for us since – as mentioned above – we want to have one and only one version of...

What operating system do I have? I stumbled across this dilemma when I needed to download a free file from the Microsoft website and was presented with two choices for my download. I could download the file in 32 bit version or 64 bit version, depending on which one suited my operating system. Also see what is 64 bit?

But the question remained, what operating system do I have? You really need to know if you have Windows XP home, Windows XP Professional, Windows Vista Home, Premium, Ultimate, or Business? The list goes on. Maybe you have Windows Seven. Also the average user has no idea what the difference is between a 32 bit operating system and a 64 bit so I will show you how to find out which one is running on your computer.

Lets start with some computer basics:

So, What REALLY Causes Urticaria and Angioedema?

We’re taught to believe urticaria and angioedema are triggered by things like perfume, dust mites, hairspray, nuts, solvents, tight clothing, pressure, cheese… even the dog!

Well, this may sound revolutionary, but after my research, I came to the following conclusion: “Urticaria sufferers are not allergic to ANYTHING!”

So why do you have urticaria attacks? Well, the simple answer is that you have an overactive immune system. Your immune system “freaks out” when it meets specific allergens. But you’re still NOT allergic!


hat does this mean? This means that dealing with the REAL problem: Your “overactive

immune system” is the problem we need to deal with. Avoiding the things that we think cause urticaria attacks, or taking drugs to kill the symptoms may temporarily help, but they are NOT the real solution.
