By the end, you should be able to fix this error and get your applications running smoothly again.

Quick Note Before You Begin

• Make sure your Windows 11 system is updated with the latest patches and security updates. Sometimes, updates fix known bugs.
• Check if you are logged in with an administrator account. Many permission errors happen because of limited user rights.
• Close all other programs before starting the troubleshooting process. This ensures no conflicting software interferes.
• Back up important files if you plan to change system settings or permissions.

Step 1: Run the Program as Administrator

Many runtime errors occur because the program does not have enough permissions to perform certain actions. Running the program as an administrator often fixes this.

1. Right-click the program’s shortcut or executable file.
2. Select Run as administrator from the context menu.
3. If prompted by User Account Control (UAC), click Yes to allow.

This method gives the program elevated privileges, allowing it to access restricted files or settings.

Step 2: Check File and Folder Permissions

If the error persists, it may be due to insufficient permissions on the files or folders the program needs.

1. Navigate to the folder or file the program is trying to access.
2. Right-click the folder or file and select Properties.
3. Go to the Security tab.
4. Click Edit… to change permissions.
5. Select your user account from the list.
6. Under Permissions, check the box for Full control.
7. Click Apply and then OK.

Adjusting permissions ensures the program can read, write, or modify the necessary files.

Step 3: Disable Antivirus or Security Software Temporarily

Sometimes, antivirus or security software blocks programs from accessing files, causing Access Denied errors.

1. Open your antivirus or security software.
2. Find the option to temporarily disable protection or shields.
3. Turn off the protection for a short period.
4. Try running the program again.

If the program works with the antivirus disabled, you may need to add it to the software’s exception list to avoid future issues.

Step 4: Use the System File Checker Tool

Corrupted system files can cause runtime errors. Windows includes a built-in tool called System File Checker (SFC) to scan and repair these files.

1. Press Windows + S and type cmd.
2. Right-click Command Prompt and select Run as administrator.
3. In the command window, type sfc /scannow and press Enter.
4. Wait for the scan to complete. It can take several minutes.
5. If any corrupt files are found, SFC will attempt to repair them automatically.

After the scan finishes, restart your computer and check if the error still appears.

Step 5: Modify User Account Control (UAC) Settings

User Account Control can sometimes prevent programs from running correctly, especially those that require elevated permissions.

1. Press Windows + S, type UAC, and select Change User Account Control settings.
2. In the window that opens, move the slider down to Never notify.
3. Click OK and restart your computer.

Lowering UAC temporarily can help determine if it causes the Access Denied error. Remember to reset it back to the previous level after troubleshooting.

Step 6: Check for Windows Updates

Microsoft regularly releases updates that fix bugs and improve system stability. Installing the latest updates can sometimes resolve runtime errors.

1. Go to Settings by pressing Windows + I.
2. Click on Windows Update in the left sidebar.
3. Click Check for updates.
4. Download and install any available updates.
5. Restart your computer after installing.

Alternative Method: Use Compatibility Mode

If you are running an older program not fully compatible with Windows 11, try running it in compatibility mode.

1. Right-click the program’s executable file and select Properties.
2. Go to the Compatibility tab.
3. Check the box for Run this program in compatibility mode for:.
4. Select an older Windows version like Windows 7 or Windows 8.
5. Click Apply and then OK.
6. Try running the program again.

FAQs

What causes Runtime Error 5 Access Denied?

This error usually occurs because the program does not have permission to access certain files or system resources. It can also happen due to antivirus interference, corrupted system files, or incompatible software.

Is it safe to run programs as administrator?

Yes, running trusted programs as administrator is safe and often necessary for them to function correctly. However, avoid giving administrator rights to unknown or suspicious programs.

Can antivirus software cause Access Denied errors?

Yes, antivirus programs sometimes block legitimate applications thinking they are threats. Temporarily disabling antivirus or adding exceptions can fix this.

How do I know which file or folder is causing the error?

The error message or program logs may indicate the file or folder being accessed. If not clear, checking permissions on the program installation folder is a good starting point.

Will resetting UAC settings affect my system security?

Lowering UAC reduces security by allowing programs to run with fewer restrictions. It’s best to use this only temporarily for troubleshooting and then restore the original settings.
