You see the message “This app can't run on your PC” when trying to launch a program, and it's frustrating — especially if you know the app should work. This error usually means there's a mismatch between the app and your system's architecture, file corruption, or compatibility issues. The good news? It's often fixable. Here's how to resolve it step by step.

1. Check System Architecture (32-bit vs 64-bit)

One of the most common causes is trying to run a 64-bit application on a 32-bit version of Windows (or vice versa in rare cases).

How to check:

• Press Win I to open Settings.
• Go to System > About .
• Look for System type under Device specifications.

What to do:

• If your system is 32-bit, you can only run 32-bit apps. You cannot run 64-bit applications.
• If the app you're trying to install is 64-bit only, you'll need to either:
  • Find a 32-bit version of the app (if available).
  • Upgrade your operating system to 64-bit Windows (requires a clean install and a compatible processor).

?? Note: You can't switch from 32-bit to 64-bit without reinstalling Windows — even if your processor supports it.

2. Run the App in Compatibility Mode

Some older programs aren't optimized for your version of Windows. Compatibility mode can help.

Steps:

• Right-click the app's executable (.exe) file.
• Select Properties .
• Go to the Compatibility tab.
• Check Run this program in compatibility mode for .
• Choose an earlier version of Windows (eg, Windows 7 or 8).
• Optionally, check Run this program as an administrator .
• Click Apply , then OK and try running the app again.

? Tip: If you're not sure which version to pick, try Windows 8 first, then Windows 7.

3. Verify the App and System Requirements

Make sure the app is designed for your version of Windows.

• Visit the developer's website and check the system requirements.
• Confirm whether the app supports your Windows version (eg, Windows 10, 11, etc.).
• Also verify if the app requires specific frameworks like .NET, Visual C Redistributables, or DirectX.

If missing dependencies are the issue:

• Download and install the required runtime libraries from Microsoft's official site.
• Avoid third-party "fix" tools that claim to install all redistributables — they can include malware.

4. Check for Corrupted or Incomplete Files

If the app file is incomplete or damaged (common with downloads or copies), Windows may block it.

What to do:

• Re-download the application from the official source.
• If it's a portable app, ensure the entire folder was copied correctly.
• Scan the file with Windows Defender or another trusted antivirus — sometimes malware disguises itself as legitimate software and gets blocked.

Also:

• Right-click the .exe file > Properties .
• At the bottom, if you see This file came from another computer and might be blocked , click Unblock before running.

5. Update Windows

An outdated system may lack necessary updates or security patches needed to run newer apps.

To update:

• Go to Settings > Windows Update .
• Click Check for updates and install any pending ones.
• Restart your PC after installing updates.

Sometimes a single cumulative update resolves compatibility issues with newer software.

6. Temporarily Disable Antivirus or Security Software

Overzealous antivirus programs can block legitimate apps, especially cracked or less-known ones.

• Disable your antivirus/firewall temporarily (just long enough to test).
• Try running the app again.
• If it works, add the app to your antivirus's exclusion list instead of leaving protection off.

?? Only do this with files you trust.

7. Use Program Install and Uninstall Troubleshooter

Windows includes a built-in tool that can fix common app installation issues.

How to access it:

• Go to Settings > System > Troubleshoot > Other troubleshooters .
• Find Programs and click Run .
• Follow the prompts to let Windows detect and fix issues.

Final Thoughts

The “This app can't run on your PC” error usually comes down to architecture mismatch, compatibility, or file issues. Start by checking your system type and app requirements, then try compatibility mode and re-downloading the file. Most cases are resolved with one of these steps.

Basically, don't assume the app or your PC is broken — it's often a simple mismatch or setting that can be fixed in minutes.
