Computers running 64-bit versions of Windows generally have more resources such as processing power and memory, than their 32-bit predecessors. Also, 64-bit applications can access more memory than 32-bit applications (up to 18.4 million Petabytes). Therefore, if your scenarios include large files and/or working with large data sets and your computer is running 64-bit version of Windows, 64-bit is the right choice when:
You're using add-ins with Outlook, Excel, or other Office apps. While 32-bit applications can work with add-ins, they can use up a system's available virtual address space. With 64-bit apps, you have up to 128 TB of virtual address space which the app and any add-ins running the same process can share. With 32-bit apps, you might get as little as 2 GB of virtual address space which in many cases isn't enough and can cause the app to stop responding or crash.
You have 32-bit COM Add-ins with no 64-bit alternative. You can continue to run 32-bit COM add-ins in 32-bit Microsoft 365 on 64-bit Windows. You can also try contacting the COM Add-in vendor and requesting a 64-bit version.
You have 32-bit MAPI applications for Outlook. With a growing number of 64-bit Outlookcustomers, rebuilding 32-bit MAPI applications, add-ins, or macros for 64-bit Outlook is the recommended option, but if needed you can continue to run them with 32-bit Outlook only, as well. To learn about preparing Outlook applications for both 32-bit and 64-bit platforms, see Building MAPI Applications on 32-Bit and 64-Bit Platforms and the Outlook MAPI Reference.
You need 32-bit Microsoft Access .mde, .ade, and .accde database files. While you can recompile 32-bit .mde, .ade, and .accde files to make them 64-bit compatible, you can continue to run 32-bit .mde, .ade, and .accde files in 32-bit Access.
You need 32-bit Microsoft Access.mde, .ade, and .accde database files. While you can recompile 32-bit .mde, .ade, and .accde files to make them 64-bit compatible, you can continue to run 32-bit .mde, .ade, and .accde files in 32-bit Access.
You work with extremely large data sets, like enterprise-scale Excel workbooks with complex calculations, many pivot tables, connections to external databases, and using Power Pivot, Power Map, or Power View. The 64-bit version of Microsoft 365 may perform better for you.
You have 32-bit MAPI applications for Outlook. With a growing number of 64-bit Outlook customers, rebuilding 32-bit MAPI applications, add-ins, or macros for 64-bit Outlook is a recommended option. To learn more about preparing Outlook applications for both 32- and 64-bit platforms, see Building MAPI applications on 32-Bit and 64-Bit Platforms and the Outlook MAPI Reference.
Your organization requires that Hardware Data Execution Prevention (DEP) be enforced for Microsoft 365 applications. DEP is a set of hardware and software technologies that some organizations use to enhance security. For 64-bit installations DEP will always be enforced, while on 32-bit installations DEP needs to be configured through settings.
With more Outlook customers using 64-bit, rebuilding 32-bit Messaging Application Programming Interface (MAPI) applications, add-ins, or macros for 64-bit Outlook is the recommended option. But if necessary you can also continue to run them with 32-bit Outlook only.
If your organization needs to continue to use extensions to Microsoft 365, such as ActiveX controls, third-party add-ins, in-house solutions built on previous versions of Microsoft 365, or 32-bit versions of software that interface directly with Microsoft 365, we recommend you go with the automatically installed 32-bit (x86) Office 2010 on computers that are running both 32-bit and 64-bit supported Windows operating systems.
You use 32-bit controls with no 64-bit alternative. You can continue to run 32-bit controls in 32-bit Microsoft 365 like Microsoft Windows Common Controls (Mscomctl.ocx, comctl.ocx), or any existing third-party 32-bit controls.
Click here to download the latest (2.43.0) 64-bit version of Git for Windows. This is the most recent maintained build. It was released about 1 month ago, on 2023-11-20.
This page contains download links for the latest released version ofPuTTY.Currently this is 0.80, released on 2023-12-18.When new releases come out, this page will update to contain thelatest, so this is a good page to bookmark or link to.Alternatively, here is apermanent link to the 0.80 release.Release versions of PuTTY are versions we think are reasonably likelyto work well. However, they are often not the most up-to-dateversion of the code available. If you have a problem with thisrelease, then it might be worth trying outthe development snapshots,to see if the problem has already been fixed in those versions.Package filesYou probably want one of these. They include versions ofall the PuTTY utilities (except the new and slightly experimentalWindows pterm).(Not sure whether you want the 32-bit or the 64-bit version? Read theFAQ entry.)
On 64-bit operating systems, Windows Installer installs and manages applications consisting of 32-bit or 64-bit Windows Installer components. The following sections describe Windows Installer on 64-bit systems.
The second bit of information, either x64-based processor or x86-based processor, indicates the hardware architecture. It's possible to install a 32-bit edition of Windows on either an x86 or x64 based system, but a 64-bit edition can only be installed on x64 hardware.
The difference between Windows 32-bit and 64-bit is processing power. A 64-bit processor can handle more data simultaneously, so it's more capable overall. Most new processors are based on the 64-bit architecture and are fully compatible with 32-bit operating systems.
To run 32-bit applications on 64-bit Windows, right-click the application and go to Properties > Compatibility. Select Run this program in compatibility mode for and choose the version in which you want to run the program.
To upgrade Windows 10 to 64-bit, you'll have to perform a clean install, so back up all your data; ensure you have a 64-bit CPU. Download the Windows Media Creation Tool to create a 64-bit Win 10 installation flash drive. Shut down your computer, plug in the flash drive, and follow the Windows setup prompts.
Or, for a quicker method, you can simply check the PROCESSOR_ARCHITECTURE environment variable. 64-bit systems will say AMD64 and 32-bit systems should say "x86". To check this you can simply echo it out:
For parallel installations of different versions use the compressed .7z archives. Make sure to extract them into an empty folder (we recommend the free software 7-Zip to extract) and create program shortcuts manually if required.
If you don't know yet whether you're on a 32- or 64-bit system, find it out with the help of our Beginners' Guide.
I find this bizarre in the extreme. First there was the (still on-going) disastrous rollout of the MacOS version "supporting" Apple Silicon (IIRC, they *still* aren't fully supporting it) and now I find out (when I need to switch platforms) that they still don't have a 64-bit version for Windows! How long has Windows supported 64-bit software? Over 20 years ago, maybe? Completely inexplicable. Definitely switching to iDrive or one of the other excellent alternatives offering 21st century support when my subscription expires.
When installing Wine on 64-bit Ubuntu 12.04, both 64-bit support and 32-bit support get installed. If I run wine foo.exe where foo.exe is a 64-bit-aware installer, it thinks it's on 64-bit Windows. This would be fine if this mode didn't fail, but in my case, it does (yet the Wine database suggests the app I'm trying to install should work, presumably as a 32-bit app).
Windows-64 (64-bit linear algebra for large data)
Unless your computer has more than 32GB of memoryand you need to solve linear algebra problemswith arrays containing more than 2 billion elements, thisversion will offer no advantage over the recommended Windows-64version above.
Windows 10 can run on both 32-bit and 64-bit processor architectures. If you have a computer with a 32-bit setup, you can upgrade to the 64-bit version without acquiring a new license. The only caveat is that there is no in-place upgrade path to make the switch. The only option is to perform a clean installation of Windows 10.
Although each version delivers the same features, when you upgrade to the 64-bit (x64) version, the device will be able to take advantage of large amounts of memory (up to 2TB) instead of the 4GB limitation with 32-bit (x86).
Accessing more memory allows you to run more apps simultaneously without affecting the experience, and you can work with a mix of 64-bit and 32-bit programs. Also, perhaps, more importantly, it will help you improve productivity on memory-intensive tasks. For instance, rendering videos, running virtual machines, and opening many tabs on your web browser.
