Resolving the Microsoft Edge Data Directory Access Error: A Step-by-Step Guide

Encountering the “Microsoft Edge can’t read and write to its data directory” error can disrupt your workflow, especially when using applications like Microsoft Power BI, Autocad, and Teams. Often, this issue arises when software installed from an admin account is accessed through a standard user account. The root cause is related to Microsoft’s WebView2, as it attempts to create a data directory without adequate permissions.

How to Resolve the Microsoft Edge Data Directory Access Error

Step 1: Use Administrator Mode

To begin, you can try running Microsoft Edge as an administrator. Right-click on the app shortcut or the executable file and select Run as administrator. If the issue persists, sign out and log back in using the Windows Administrator account. Make any required changes to the application and return to your standard user account to check if the error still exists.

Pro Tip: This simple adjustment resolves the issue for many users, so it’s a good first step.

Step 2: Repair Edge and WebView2 via Control Panel

If running the app as an administrator does not work, the next step is to repair Microsoft Edge and WebView2 through the Control Panel:

  1. Click on the Start button and search for Control Panel, then open it.
  2. Navigate to Uninstall a program.
  3. Look for Microsoft Edge, select it, and click on Change.
  4. When prompted, choose Repair to begin the process.
  5. Repeat these steps for Microsoft Edge WebView2 Runtime.
  6. Confirm if the problem has been resolved.

Pro Tip: Corrupted files in Edge or WebView2 can lead to this error; repairing them often solves the issue.

Step 3: Modify Edge Permissions with PowerShell

If you’re comfortable with advanced troubleshooting, you can use PowerShell to modify permissions for the Edge data directory:

  1. Open an elevated PowerShell window (Run as administrator).
  2. Use the following script, replacing C:\Path\To\Edge\Data with the correct path for Edge’s data directory: 
  3. $edgeDataDir = 'C:\Path\To\Edge\Data' $acl = Get-Acl $edgeDataDir $user = [System. Security. Principal. WindowsIdentity]::GetCurrent().Name $rule = New-Object System. Security. AccessControl. FileSystemAccessRule($user, 'FullControl', 'Allow') $acl. SetAccessRule($rule) Set-Acl $edgeDataDir $acl
  4. Run this script to adjust the permissions accordingly.

Pro Tip: Always back up important data before making such changes to avoid data loss.

Additional Tips

  • Ensure your software is up to date to prevent compatibility issues.
  • Consider creating a new user profile if issues persist across multiple accounts.
  • Utilize third-party tools for data directory management if needed.
