If you’ve encountered the frustrating Windows ERROR_5 (Access Denied) message, you’re not alone. This common error is a security-related issue that prevents you from accessing files, folders, or running certain applications. But don’t worry! In this guide, we’ll walk you through easy, effective solutions to get your system running smoothly again.
What is Windows ERROR_5 (Access Denied)?
Before diving into fixes, it’s important to understand what this error means. ERROR_5 usually occurs when Windows denies permission to a user or an application to access a resource. This can happen due to:
- Insufficient user permissions
- Corrupted system files
- User Account Control (UAC) restrictions
- Network access issues
- Antivirus or firewall interference
Knowing the cause helps us apply the right solution.
Step 1: Run Program as Administrator
Many times, the Access Denied error happens because the program needs elevated permissions.
How to do this:
- Right-click the program or installer giving the error.
- Select Run as administrator.
- If prompted by User Account Control (UAC), click Yes.
If this resolves your issue, you’re good to go. If not, proceed to the next step.
Step 2: Check Folder or File Permissions
Incorrect permissions or ownership can cause ERROR_5.
Follow these instructions:
- Navigate to the folder or file you cannot access.
- Right-click it and select Properties.
- Go to the Security tab.
- Click Edit to change permissions.
- Select your user account and check Full control under the Allow column.
- Click Apply, then OK.
If you encounter issues accessing the Security tab:
- Go to the Advanced tab in Properties, then click Change next to Owner.
- Type your username, click Check Names, then OK.
- Check Replace owner on subcontainers and objects, then click Apply.
Try accessing the file or folder again.
Step 3: Disable User Account Control (Temporarily)
UAC sometimes blocks apps or commands from running properly.
How to disable:
- Open the Start menu and type "UAC".
- Click Change User Account Control settings.
- Move the slider down to Never notify.
- Click OK and restart your computer.
Remember to turn UAC back on when you’re done troubleshooting for security.
Step 4: Verify Your User Account Has Administrative Privileges
If your account isn’t an admin, some operations will be denied.
To check:
- Press Win + R, type
netplwiz, and press Enter. - Select your user account and click Properties.
- Go to the Group Membership tab.
- Ensure it’s set to Administrator.
If not, you may need to log into an admin account to change it or contact your system administrator.
Step 5: Disable Antivirus or Firewall Temporarily
Sometimes security software mistakenly blocks access, causing ERROR_5.
Try this:
- Temporarily disable your antivirus or firewall software.
- Check if the issue persists.
- If resolved, add the program or file in question to the antivirus’s whitelist or firewall exceptions.
- Don’t forget to enable your security software afterward.
Step 6: Use Command Prompt to Fix System Files
Corrupted system files can trigger access errors.
Run System File Checker (SFC):
- Click Start, type cmd.
- Right-click Command Prompt, then Run as administrator.
- Type:
sfc /scannowand press Enter. - Wait for the scan to complete and follow any on-screen instructions.
- Restart your PC.
Step 7: Check Network and Shared Folder Permissions (If Applicable)
If ERROR_5 happens when accessing network resources:
- Ensure that your user account has permission for the shared folder.
- On the remote machine, check the folder’s Sharing and Security permissions.
- Try reconnecting to the network share with correct credentials.
Final Tips and Best Practices
- Create a System Restore Point before making changes.
- Always use administrator accounts for system-level tasks.
- Keep Windows updated to patch known bugs.
- Maintain regular backups to avoid data loss.

Windows ERROR_5 (Access Denied) can feel like a roadblock—but with the steps above, you can regain control quickly and easily. Whether it’s adjusting permissions or running as admin, the fixes are often straightforward. If the problem persists despite these efforts, you may want to consult professional support.
