The basic process depends on your operating system

Downloading an app on a laptop works differently on Windows, Mac, and Linux because each system has its own store or installation method. On Windows, you typically use the Microsoft Store or download directly from a website. On Mac, you use the App Store or download from a developer's website. On Linux, you use a package manager built into your system. The steps are straightforward once you know which route your laptop uses.

Before you start, know that not every app exists for every operating system. An app made for Windows won't run on Mac without special software, and vice versa. Check the app's website or store listing to confirm it works on your laptop first.

Key Takeaways

  • Windows laptops can get apps from the Microsoft Store (built-in) or directly from a developer's website by downloading an .exe or .msi file.
  • Mac laptops use the App Store (built-in) or can download apps directly from developers, which you then drag into your Applications folder.
  • Always download apps from official sources — the app's real website, the Microsoft Store, or the Mac App Store — to avoid malware.
  • After downloading, you may need to run an installer file or move the app to a specific folder before you can use it.
  • If an app won't open after installation, check that it matches your laptop's operating system and that your system is up to date.

Downloading apps on Windows through the Microsoft Store

The Microsoft Store is the safest place to get apps on Windows because Microsoft checks them before they appear. Open the Microsoft Store app (it's built into Windows 10 and later). Search for the app you want by name. Click the app in the results, then click the "Get" or "Install" button. Windows will download and install it automatically, and the app will appear in your Start menu when it's done.

The downside is that not every app is in the Microsoft Store. Popular apps like Zoom, VLC, or Slack are there, but smaller or specialized programs often aren't. If you can't find what you need, you'll download directly from the developer instead.

Downloading apps on Windows from a website

Go to the app's official website (not a third-party download site). Look for a button that says "Download" or "Download for Windows." Click it. Your browser will download a file — usually ending in .exe or .msi — to your Downloads folder. Open your Downloads folder, find the file, and double-click it. A window will appear asking you to confirm the installation. Follow the prompts, which usually just mean clicking "Next" and "Install" until the app opens.

After installation finishes, the app will appear in your Start menu. You can pin it there for quick access, or search for it by name whenever you want to open it. If you see a warning that the app is from an unknown publisher, that's normal for less common software — it doesn't mean the app is dangerous, just that it's not from a major company.

Downloading apps on Mac through the App Store

Open the App Store (it's in your Applications folder or Dock). Search for the app by name. Click the app in the results, then click the "Get" button. You may be asked to sign in with your Apple ID. Once you do, the button changes to "Install," and the app downloads and installs automatically. The app will appear in your Applications folder and Launchpad when it's done.

Like the Microsoft Store, the Mac App Store doesn't have every app. Many developers distribute their software directly instead, which means you download it from their website.

Downloading apps on Mac from a website

Go to the app's official website and look for a "Download" button. Click it. Your browser will download a file, usually ending in .dmg (a disk image) or .zip. Open your Downloads folder and double-click the file. If it's a .dmg file, a window opens showing the app icon. Drag the app icon into the Applications folder (you'll see it in the same window). If it's a .zip file, your Mac automatically unpacks it, and you can drag the app to Applications the same way.

Once the app is in your Applications folder, you can open it by searching for it in Spotlight (press Command + Space, type the app name, and press Enter) or by opening Applications in Finder and double-clicking it. The first time you open an app from a website, Mac may ask if you're sure you want to open it — click "Open" to proceed.

What to do if an app won't open after you install it

First, make sure you downloaded the right version for your operating system. A Windows app won't run on Mac, and vice versa. Check the app's website or the store listing to confirm. Second, check that your laptop's operating system is current. Some apps need a recent version of Windows or macOS to work. On Windows, go to Settings > System > About and look for "Update." On Mac, go to System Settings > General > Software Update.

If the app still won't open, try restarting your laptop. If that doesn't work, uninstall the app and download it again from the official source. On Windows, go to Settings > Apps > Apps & Features, find the app, and click "Uninstall." On Mac, open Applications in Finder, right-click the app, and click "Move to Trash."

Staying safe when you download apps

Always download from the official source: the app's real website, the Microsoft Store, or the Mac App Store. Avoid third-party download sites that claim to host the app, because they sometimes bundle malware or outdated versions. If you're unsure whether a website is official, search for the app name plus "official download" to find the real one.

Before you download, read the app's permissions. On Windows and Mac, apps will ask for access to your camera, microphone, files, or location. If an app asks for permission to something it doesn't need — like a calculator asking for your contacts — that's a red flag. You can also check reviews on the Microsoft Store or Mac App Store to see if other users report problems.

Frequently Asked Questions

Can I download an app on my laptop if I don't have an internet connection?

No. You need an internet connection to download the app file from the store or website. Once it's installed, many apps work offline, but the initial download requires internet. If your connection is slow, the download may take a while, but you can usually leave it running in the background.

What's the difference between downloading an app and installing it?

Downloading means getting the file onto your laptop. Installing means setting it up so it actually works. Usually these happen together — you download an installer file, run it, and the app installs automatically. On Mac, you sometimes download a file and then manually drag it to Applications, which is the installation step.

Do I need to pay for every app I download?

No. Many apps are free, and both the Microsoft Store and Mac App Store clearly show the price (or "Free") before you download. Some free apps show ads or ask you to pay for extra features later. Read the description before downloading to understand what you're getting.

Can I download the same app on multiple laptops?

Yes, if you own the app or it's free. If you bought an app from the Microsoft Store or Mac App Store, you can install it on other laptops using the same account. For apps you download from websites, check the developer's terms — most let you install on your own devices, but some limit how many computers you can use it on.

What should I do if a download seems stuck?

Wait a few minutes — large files take time. If it's still stuck after 10 minutes, close your browser and try again. If the problem continues, restart your laptop and try downloading from a different browser. If the app's website is down, try again later.
