How to Fix Power BI Error Access to Path Not Working on Windows 11: Step-by-Step Solutions

Power BI is a powerful tool for data visualization and analysis. However, sometimes users encounter errors that disrupt their workflow. One common issue on Windows 11 is the “Access to Path Not Working” error.

This error usually means that Power BI cannot access a specific file or folder needed for your project. It can be caused by permission problems, corrupted files, or software conflicts.

In this article, we will guide you through simple, step-by-step solutions to fix this error and get Power BI running smoothly again on your Windows 11 system.

Each step is explained clearly, so even if you are not very technical, you can follow along easily.

Quick Note: Prerequisites and Initial Checks

Before diving into the troubleshooting steps, make sure you have the following checked:

  • You are logged in as an administrator on your Windows 11 computer.
  • Power BI Desktop is updated to the latest version.
  • The file or folder you are trying to access is not open in another program.
  • Your Windows 11 system is up to date with the latest security and software updates.

These simple checks can often prevent basic permission and access issues.

Step 1: Run Power BI as Administrator

Sometimes, Power BI needs elevated permissions to access certain paths or files. Running it as an administrator can solve this.

  1. Close Power BI Desktop if it is open.
  2. Click the Start button on your Windows 11 taskbar.
  3. Type Power BI Desktop in the search bar.
  4. Right-click the Power BI Desktop app icon and select Run as administrator.
  5. Try to open your file or project again and see if the error persists.

This step is important because administrator rights allow the app to bypass some file access restrictions.

Step 2: Check File or Folder Permissions

If running as administrator does not help, the issue might be related to file permissions. You need to ensure that your user account has the necessary rights.

  1. Navigate to the folder or file Power BI 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. Find your user name in the list and make sure Full Control or at least Read & Execute permissions are checked.
  6. If your user name is not listed, click Add, enter your user name, and grant the necessary permissions.
  7. Click Apply and then OK.
  8. Restart Power BI and check if the error is resolved.

Giving proper permissions ensures Power BI can access and modify files as needed for your work.

Step 3: Clear Power BI Cache and Temporary Files

Sometimes, corrupted cache or temporary files can cause access issues. Clearing these can help fix the problem.

  1. Close Power BI Desktop.
  2. Press Windows + R to open the Run dialog.
  3. Type %localappdata%MicrosoftPower BI DesktopAnalysisServicesWorkspaces and press Enter.
  4. Delete all folders inside this directory. These are temporary workspaces Power BI uses.
  5. Next, open the Run dialog again and type %temp% to open the Temp folder.
  6. Delete unnecessary files here to clear temporary files.
  7. Restart your computer and launch Power BI again.

Clearing cache and temporary files removes corrupted data that might block file access.

Step 4: Disable Antivirus or Windows Defender Temporarily

Sometimes, antivirus programs or Windows Defender may wrongly block Power BI from accessing certain files or folders.

  1. Temporarily disable your third-party antivirus software. Usually, you can do this from the antivirus icon in the system tray.
  2. To disable Windows Defender temporarily:
    • Click Start and type Windows Security.
    • Open Windows Security and go to Virus & threat protection.
    • Click on Manage settings under Virus & threat protection settings.
    • Turn off Real-time protection.
  3. Try opening Power BI and see if the error disappears.
  4. Remember to re-enable your antivirus and Windows Defender after testing to keep your system safe.

This step helps identify if security software is causing the access problem.

Step 5: Check Path Length and Folder Names

Windows has a maximum path length limit (260 characters). If the file or folder path is too long or contains special characters, Power BI might not access it properly.

  1. Locate the file or folder Power BI is trying to access.
  2. Check the full path length. This includes all folder names plus the file name.
  3. If the path is very long, try moving the file to a folder closer to the root directory. For example, move it from C:UsersYourNameDocumentsVeryLongFolderName... to C:PowerBIProjects.
  4. Rename any folders or files to remove special characters like &, %, $, or spaces.
  5. Open Power BI and try again.

Shortening the path and cleaning names helps Windows and Power BI handle file access properly.

Step 6: Repair or Reinstall Power BI Desktop

If none of the above work, your Power BI installation might be corrupted. Repairing or reinstalling the software can fix deeper issues.

  1. Press Windows + I to open Settings.
  2. Go to Apps > Installed apps (or Apps > Apps & features).
  3. Find Power BI Desktop in the list.
  4. Click the three dots next to it and select Modify or Repair if available.
  5. Follow the on-screen instructions to repair.
  6. If repair is not an option, uninstall Power BI Desktop.
  7. Download the latest version from the official Power BI website and reinstall.
  8. Restart your computer and check if the error is resolved.

Repairing or reinstalling restores damaged program files and settings.
