Can I Use 32 Bit on 64 Bit
Your computer is probably running a 64-bit version of Windows. But take a look at Task Managing director and you'll see that many apps on your system are notwithstanding 32-bit. Is this a trouble?
Most modernistic computers—definitely those sold since around the Windows 7 days—are 64-bit capable and send with a 64-bit version of Windows. If you're unsure nigh your own PC, it's easy to check whether y'all're running 32-bit or 64-bit Windows. In that location are many differences betwixt 64-fleck and 32-bit versions of Windows—plenty that if your PC and apps back up it, you should exist running the 64-bit version. Even if every app you run is a 32-fleck app, running a 64-fleck Bone is even so going to be more secure and reliable.
Merely, what about those apps? Things go a bit trickier, there. The first thing to know is that 64-scrap versions of Windows can run 32-bit apps, but 32-scrap versions of Windows tin can't run 64-bit software. Another trivial wrinkle—and one that applies only to a very small number of people—is that 32-bit versions of Windows tin can run sometime 16-fleck apps, but those 16-scrap apps will not run on a 64-bit version of Windows. Then, let's dive into that a scrap more than and run across when it might affair to you.

You can use Task Manager to see which of your programs are 64-bit and which are 32-scrap. To open it, right-click any open expanse on the taskbar, and so click "Task Manager" (or press Ctrl+Shift+Escape).
On the "Processes" tab, take a look under the "Name" cavalcade. If you're using a 64-bit version of Windows 8 or 10, yous'll see the text "(32-bit)" subsequently the name of any 32-bit app. If you lot're using a 64-bit version of Windows seven, y'all'll run across the text "*32" instead. In all versions, 64-scrap apps accept no extra text later on the proper name.
Windows besides installs 32-chip and 64-bit apps in different places—or at least, tries to. 32-bit apps are ordinarily installed to the C:\Program Files (x86)\ folder on 64-bit versions of Windows, while 64-bit programs are usually installed to the C:\Program Files\ binder.
This is more of a guideline, though. There'due south no rule forcing 32-fleck and 64-flake apps into their respective folders. For instance, the Steam customer is a 32-fleck program, and information technology gets installs properly into the C:\Program Files (x86)\ folder by default. Merely, all games you install through Steam are installed to the C:\Program Files (x86)\Steam binder past default—even 64-bit games.
If you compare your two dissimilar Program Files folders, you'll notice that virtually of your programs are probably installed to the C:\Programme Files (x86) binder. They're probable 32-bit programs.
Is Running 32-bit Apps on 64-bit Windows a Bad Idea?
RELATED: Why the 64-chip Version of Windows is More Secure
On the surface, it might seem like running 32-flake apps in a 64-bit environment is bad—or less than ideal, anyway. Later all, 32-bit apps aren't taking total advantage of the 64-bit compages. And it'due south true. When possible, running a 64-bit version of the app provides additional security features to apps that are likely to come under attack. And 64-scrap apps tin can access much more than memory direct than the four GB that 32-fleck apps can access.
Still, these are differences that you're just non likely to notice running regular apps in the real world. For example, yous're non going to endure any kind of performance punishment past running 32-bit apps. In a 64-bit version of Windows, 32-bit apps run nether something named the Windows 32-chip on Windows 64-bit (WoW64) compatibility layer—a total subsystem that handles running 32-bit apps. Your 32-bit Windows programs will run about the same every bit they would on a 32-fleck version of Windows (and in some cases, even better), so in that location'south no downside to running these programs on a 64- chip OS.

Even if every programme you use is even so 32-scrap, you'll benefit because your operating system itself is running in 64-flake manner. The 64-flake version of Windows is more secure.
But 64-flake Programs Would Exist Better, Right?
As we mentioned earlier, in that location is an advantage to running the 64-scrap version of an app, if one is available. On a 64-bit version of Windows, 32-bit programs tin only access four GB of retention each, while 64-bit programs tin can admission much more than. If a program is likely to come under assault, the additional security features practical to 64-bit programs can help.
Many apps offer both 32-bit and 64-bit versions. Chrome, Photoshop, iTunes, and Microsoft Office are a few of the near popular Windows programs, and they're all available in 64-fleck form. Demanding games are oft 64-bit so they can use more memory.
Many apps haven't made the leap, though, and most never will. Yous tin can yet run nigh 10-twelvemonth-old 32-bit Windows programs on a 64-fleck version of Windows today, even if their developers haven't updated them since 64-bit versions of Windows came along.
A developer that wants to provide a 64-chip version of their plan has to do additional piece of work. They have to brand sure the existing code compiles and runs correctly as 64-bit software. They have to provide and support two separate versions of the program, every bit people running a 32-flake version of Windows can't use the 64-bit version.
And in many apps, people just wouldn't notice a difference anyway. Let'south accept the Windows desktop version of Evernote equally an example here. Even if they provided a 64-bit version of Evernote, users likely wouldn't notice a departure at all. The 32-bit plan can run just fine on a 64-bit version of Windows, and there'd be no noticeable advantages with a 64-bit version.
In brusque, if you have a choice, definitely grab the 64-flake version of your app. If you don't take a selection, go the 32-chip version and don't worry about it.
Getting 64-fleck Apps
How you go 64-fleck apps when they're available differs based on the app. Sometimes, when y'all go to a download page for an app, the page will find whether you're using a 32-flake or 64-bit version of Windows and automatically direct yous to the correct installer. Apple tree iTunes works this way.
Other times, you'll download a unmarried installation app that contains both the 32-fleck and 64-flake versions of the app. When you launch the installer, information technology will detect at that point whether yous're using a 32-bit or 64-bit version of Windows and install those files. Photoshop for Windows works this way.
And still other times, yous'll actually get a choice on the app's download page to download the version you desire. Sometimes the version will say "64-bit," sometimes it will say "x64," and sometimes both. When you encounter a choice like this, get ahead and download the 64-scrap version.
In the end, what's of import isn't making sure you lot're running 64-bit apps—it's making sure you're running apps that work well for you. If at that place's a 64-bit version of an app, by all means use it. If not, using the 32-bit version is just fine. For nigh apps, you won't even detect the deviation.
