| Learn how to check software system requirements and confirm compatibility with Windows, macOS, and Linux before installation. |
Downloading a program only to see "This app can't run on your PC" is one of the more frustrating moments in software installation — especially after waiting for a large file to finish downloading. Checking compatibility first takes just a couple of minutes and avoids the whole problem.
This guide covers exactly how to check whether a piece of software will run on your Windows PC before you install it, including where to find your system specs and how to read a program's stated requirements correctly.
Before You Start: Quick Checklist
- Have the software's official system requirements page open. Every legitimate program lists minimum (and often recommended) requirements on its official website.
- Know you'll need a few specific details. Windows version, 32-bit vs. 64-bit, available storage, RAM, and sometimes graphics card details.
- Check requirements before downloading, not after. This avoids wasting time and bandwidth on a large installer that won't run anyway.
Step 1: Find Your Windows Version and System Type
Most software requirements start with a minimum Windows version, so this is the first thing to check.
- Select Start > Settings > System > About.
- Under Windows specifications, note your edition and version (for example, Windows 11 Home, version 24H2).
- Under Device specifications > System type, confirm whether you're running a 32-bit or 64-bit operating system.
You can also press Windows key + R, type winver, and press Enter for a quick summary. Microsoft's official page on checking your Windows version covers a few additional methods if you need more detail.
Step 2: Check Your Hardware Specs
Beyond the operating system, most software also lists minimum hardware requirements — processor, memory, and available storage.
- Go to Settings > System > About to see your processor, installed RAM, and system type in one place.
- For more detailed hardware information, including your graphics card, press Windows key + R, type
dxdiag, and press Enter to open the DirectX Diagnostic Tool. - To check available storage, go to Settings > System > Storage.

Step 3: Compare Against the Software's Stated Requirements
Once you know your own specs, compare them against what the software actually requires. Most official product pages list this as two tiers:
| Requirement type | What it means |
|---|---|
| Minimum requirements | The lowest specs the software will run on at all — often with reduced performance or features disabled |
| Recommended requirements | The specs needed for the software to run smoothly, especially for demanding programs like games or video editors |
Meeting only the minimum requirements usually means the software will run, but not necessarily run well — this matters most for resource-heavy programs like games, video editing tools, or 3D design software. For lighter everyday apps, minimum requirements are typically enough.
Step 4: Check Processor Architecture (x64 vs. ARM)
Most Windows PCs use standard x64 processors, but an increasing number of newer laptops use ARM-based chips (common in some Surface and other slim laptops). Software built specifically for x64 doesn't always run natively on ARM devices, though many run through built-in emulation with a possible performance cost. If you're on an ARM-based PC, check the software's requirements page specifically for ARM or "Windows on ARM" support before installing.
Step 5: Use Compatibility Mode for Older Software
If a program was built for an older version of Windows, it may still run using compatibility settings rather than requiring a fully updated version.
- Right-click the program's installer or shortcut and select Properties.
- Go to the Compatibility tab.
- Check Run this program in compatibility mode for and select an earlier Windows version from the list.
- Apply the changes and try running the program again.
This doesn't guarantee older software will work perfectly, but it resolves compatibility issues for a meaningful number of legacy programs.
Common Types of Compatibility Issues
Not all compatibility problems come from the same source. Knowing which category you're dealing with makes troubleshooting faster:
- Operating system version: The software requires a newer (or sometimes older) Windows version than what's installed.
- Architecture mismatch: A 64-bit-only installer won't run on a 32-bit system, and some x64 software has limited or no support on ARM-based PCs.
- Insufficient hardware: Not enough RAM, an underpowered processor, or a graphics card that doesn't support a required feature (common with games and 3D applications).
- Missing dependencies: Some software needs a separate runtime or framework installed first, such as a specific version of .NET or Visual C++ Redistributables, which the installer sometimes prompts you to install automatically.
- Driver-related issues: Occasionally, software runs but behaves incorrectly because a graphics or hardware driver is outdated rather than the software itself being incompatible.
Troubleshooting Compatibility Errors
If you install software and see an error like "This app can't run on your PC," or the program crashes immediately on launch, a few things are worth checking:
- Double-check 32-bit vs. 64-bit. Installing the wrong version for your system type is one of the most common causes of this exact error.
- Confirm your Windows version meets the minimum. Some software explicitly blocks installation on unsupported Windows versions.
- Try compatibility mode for older software, as described above.
- Check for a pending Windows update. Some compatibility issues are resolved by installing the latest Windows updates first — see our guide on how to update software on your computer for the full process.

Why Checking Compatibility Matters
Beyond avoiding a failed install, running software on hardware that doesn't meet its requirements can lead to instability, crashes, or in worse cases, corrupted files if the program fails mid-task. Checking requirements first is a small step that avoids a much bigger headache later.

Frequently Asked Questions
What happens if I install software that isn't compatible with my PC?
Depending on the specific mismatch, the installer may simply refuse to run, the software may install but crash or run poorly, or in some cases the installation may fail partway through. It's rarely harmful to your system, just non-functional.
How do I know if software needs 32-bit or 64-bit Windows?
Check the software's system requirements page — most modern programs specify this directly, and many now offer only a 64-bit version, since most PCs sold in recent years run 64-bit Windows.
Can I run software designed for an older version of Windows?
Often yes, using Compatibility Mode, though results vary depending on how the software was built. Some older programs run perfectly this way, while others may still have issues due to deeper changes in how modern Windows works.
Do I need to check compatibility for apps from the Microsoft Store?
Less so — the Microsoft Store only shows apps compatible with your specific device and Windows version, filtering out anything that wouldn't work. Compatibility checks matter most for software downloaded directly from a developer's website.
Why does software sometimes run slowly even though it meets the minimum requirements?
Minimum requirements describe the lowest specs a program will run on at all, not the specs needed for smooth performance. For resource-intensive software, aiming for the recommended requirements rather than the minimum gives a much better experience.
What is a "dependency" and why does it affect compatibility?
A dependency is a separate piece of software a program needs to function, such as a specific runtime framework. If a required dependency is missing, the installer often prompts you to install it automatically, but occasionally you'll need to download and install it separately before the main software will run.
