This guide will walk you through simple, step-by-step solutions to resolve this error. Each step is explained in a straightforward way to help even beginners follow along.
By following these instructions, you should be able to open your files or install your programs without trouble. Let’s get started with some quick checks before diving into the fixes.
Read carefully and take your time to perform each step for the best results.
Quick Note: Prerequisites and Checks
- Check your internet connection: A stable internet connection is important because some fixes require downloading updates or files.
- Make sure your Windows 11 is up to date: Running the latest system updates helps prevent compatibility issues.
- Have administrator rights: Some steps require you to run commands or change settings that need admin access.
- Backup important files: It’s always good practice to backup your data before making system changes.
Step 1: Restart Your Computer
Before trying anything complicated, restart your computer. This simple action can fix temporary glitches causing the error.
Why? Restarting clears memory and stops any background processes that may interfere with launching applications.
After restarting, try opening the file or application again.
Step 2: Run the File or Application as Administrator
Sometimes, the error occurs because the program needs higher permissions to run.
- Right-click the file or program icon.
- Select Run as administrator.
- If prompted by User Account Control (UAC), click Yes to allow.
Why? Running as administrator gives the program necessary permissions to function properly, avoiding security blocks.
Step 3: Check for Digital Signature Issues
The error can happen if Windows suspects that the file’s publisher cannot be verified.
- Right-click the file and select Properties.
- Go to the Digital Signatures tab.
- If the tab is missing or the signature is invalid, the file might be unsafe or corrupted.
What to do next? Only proceed if you trust the source. Otherwise, avoid opening the file.
Step 4: Temporarily Disable Windows Defender SmartScreen
Windows SmartScreen can block applications from unknown publishers. You can disable it temporarily to test if it’s causing the issue.
- Press Windows key + I to open Settings.
- Navigate to Privacy & Security > Windows Security > App & Browser Control.
- Under Reputation-based protection, click Turn off for SmartScreen for apps and files.
- Try opening your file again.
Remember: Turn SmartScreen back on after testing to keep your PC safe.
Step 5: Unblock the File
Windows may block files downloaded from the internet to protect your PC.
- Right-click the file and select Properties.
- At the bottom of the General tab, look for a checkbox or button labeled Unblock.
- Check the box or click the button, then click Apply and OK.
- Try opening the file again.
This step tells Windows you trust the file and removes the block.
Step 6: Scan for Malware
Malware or viruses can cause unexpected errors.
- Open Windows Security from the Start menu.
- Click on Virus & Threat Protection.
- Run a Quick Scan or Full Scan.
- Follow the instructions if any threats are detected.
Removing malware helps ensure the error is not caused by malicious software interfering with your system.
Step 7: Use the System File Checker (SFC) Tool
Corrupted system files can cause errors. The SFC tool checks and repairs these files.
- Press Windows key + S, type cmd, then right-click Command Prompt and select Run as administrator.
- Type the following command and press Enter:
sfc /scannow
This process may take some time. Once completed, it will display if it found and fixed any issues.
Restart your computer and try opening your file again.
Step 8: Update or Reinstall the Application
If the error appears when using a specific program, updating or reinstalling it might help.
- Open Settings > Apps > Installed apps.
- Find the application causing the error.
- Click on it and select Modify or Uninstall.
- Download the latest version from the official website and install it.
Outdated or corrupted applications can trigger errors that updates or fresh installs can fix.
Alternative Methods and Advanced Options
If the above steps don’t solve the problem, consider these advanced methods:
- Create a new user account: Sometimes user profile issues cause errors. Setting up a new account can help identify this.
- Perform a clean boot: This starts Windows with minimal drivers and startup programs, helping isolate conflicting software.
- Check Event Viewer: Use Event Viewer to find detailed error logs that might give clues.
