Are you getting the Audacity error 0x1x when trying to launch the app? The full message often reads:

This typically means a file is missing, corrupt, or incompatible with your system. Here’s a simple step-by-step guide to fix it.

Step 1: Run System File Checker (SFC)

System files might be damaged or missing.

1. Press Windows + S, type cmd.
2. Right-click Command Prompt, choose Run as administrator.
3. Type the following and hit Enter: sfc /scannow
4. Let the scan finish. If any issues are found, they’ll be automatically repaired.

Step 2: Reinstall Audacity

Corrupted installations are a major cause of launch errors.

1. Press Windows + R, type: appwiz.cpl
2. Locate Audacity in the list, uninstall it.
3. Open File Explorer and delete the leftover folder: C:\Program Files (x86)\Audacity\
4. Download the latest version from the official Audacity website.
5. Run the installer as administrator and complete setup.

Step 3: Repair Microsoft Visual C++ Redistributables

Audacity depends on Visual C++ libraries.

1. Go to Control Panel > Programs > Programs and Features.
2. Scroll to all entries named Microsoft Visual C++ Redistributable.

Keeping Windows updated ensures compatibility.

Step 5: Scan for Malware

Sometimes malware blocks apps from launching.

2. Run a full system scan.
3. Quarantine any threats found.
4. Restart and try launching Audacity again.

Step 6: Install DirectX Runtime (Optional)

Some systems miss key audio-related components.

1. Download the DirectX End-User Runtime Web Installer.
2. Install it and restart your PC.

Step 7: Run Audacity as Administrator

Still stuck? Try this simple trick.

1. Right-click on the Audacity shortcut or executable.
