How to Fix This App Can't Run on Your PC Error on Windows 11/10 (2026 Guide)

It’s frustrating when Windows displays the blunt message “This app can’t run on your PC,” especially when the cause isn’t clear. The good news is that, in most cases, it comes down to a compatibility or permission issue—and you can resolve it quickly by following the guide below.

Here are the most common reasons:

• Architecture mismatch: The app doesn’t match your PC (e.g., ARM app on x64, or 64-bit app on 32-bit Windows).

• Unsupported Windows version: Older or specialized apps may not run on Windows 10/11.

• Blocked by Windows security (SmartScreen/Defender): Windows may stop unsigned, unrecognized, or untrusted apps from running.

• Corrupted or incomplete file: A damaged download can prevent Windows from executing the app.

• Insufficient user permissions: The app may require administrator rights or specific system access.

• S Mode restrictions (Windows 10/11 S Mode): Only Microsoft Store apps are allowed, blocking traditional .exe files.

Now that you understand the possible causes, the next step is to identify the root of the problem so you can apply a more targeted fix.

Check if You're Using the 32-bit, 64-bit, or ARM64 Version

Not all apps are compatible with every system type. For example, a 64-bit application won’t run on a 32-bit version of Windows. Always match the app’s architecture to your system.

How to find your system type:

1. Press Windows key + I to open Settings.

2. Go to System > About.

3. Under Device specifications, look at System type.

Now compare it with the app version:

• x64 apps → a standard Intel or AMD PC, run 32-bit and most 64-bit apps.

• ARM64 apps → required for ARM devices (like some Snapdragon laptops).

Update Your Windows 10 Operating System

An outdated system can lead to compatibility issues, so make sure your OS is up to date.

1. Press Windows + I to open Settings.

2. Go to Windows Updates > Click Check for Updates.

Find Which App is Triggering the Error

If the error appears randomly and you’re unsure which app is responsible, here’s how to find out:

1. Press Win + X > Event Viewer.

2. Go to Windows Logs > Application

3. Look for an error entry with a red "Error" icon at the timestamp.

4. Click on the event and check the details to find the .exe file name.

If you’re looking for a quick solution, start with these proven fixes:

Run the App as Administrator

Right-click the app, select Properties > Compatibility tab > check "Run this program as an administrator" > OK. This instantly cures many permission-related blocks.

Enable Compatibility Mode (Windows 7/8)

Right-click the app, select Properties > Compatibility tab > check "Run this program in compatibility mode for" > select an older OS like Windows 8 or Windows 7 > OK.

Create a New Administrator Account

A new user profile can bypass issues caused by corrupted settings or incorrect permissions that may prevent apps from running properly.

1. Press Windows + I to open Settings.

2. Go to Accounts > click Family & other users > Add account (or Add someone else to this PC)

3. Click "I don’t have this person’s sign-in information" this link.

4. Then click Add a user without a Microsoft account (for a local account).

5. Enter a username and password, then click Next.

Temporarily Disable Windows Defender SmartScreen

1. Open Windows Security from the Start menu.

2. Click App & browser control.

3. Under Smart App Control or Reputation-based (Win 10) protection, click the Reputation-based protection settings link.

4. Look for Check apps and files. Change the setting from Block to Warn (if available) or temporarily turn it off.

⚠️ Important:

• Try launching the app again. If it works, SmartScreen was likely blocking it.

• Disable this feature only temporarily, and re-enable it after installing the app.

Turn on Developer Mode in Windows Settings

Some apps (especially unsigned or side-loaded UWP/modern packages) require Developer Mode.

1. Press Windows key + I to open Settings.

2. Click System, then scroll down and select For developers (on Windows 10, it’s under Update & Security > For developers).

3. Turn on Developer Mode.

4. Click Yes to confirm the prompt.

5. No restart is needed; launch your app again.

If the issue persists, try these deeper fixes.

Run SFC /scannow to Repair System Files

Corrupted system files can stop apps from launching, especially built-in Windows tools. Running the SFC scan can detect and repair these issues.

1. Type cmd in the search bar, right-click Command Prompt, and choose Run as administrator.

2. Enter the command sfc /scannow and press Enter.

3. Wait for the scan to finish, then restart your computer.

Re-download the Application (Corrupted File Fix)

If the installer is corrupted or incomplete, Windows may block it from running. To fix this, first remove any partially installed version of the program—simply deleting its folder can leave behind registry entries and leftover files. For a cleaner uninstall, you can use a dedicated tool like IObit Uninstaller to remove residual data. Then delete the old installer and download a fresh copy from the official website.
