Windows Media Player is a built-in tool in all Windows operating systems that enables you to open and use audio and video files of various formats. It’s a great simple tool that will meet the needs of most casual users.
Despite its simplicity, there are serious errors users have to deal with on a daily basis and the one in the title is not different. It occurs when users are trying to open a file with Windows Media Player and it prevents you from opening it. Follow the solutions below in order to fix this.
Solution 1: System Restore
Even though System Restore is thought of as a last resort, it really does not do anything much to change your overall experience as you can adjust it to only go back several days, just before the error started to occur.
This method was highly successful when it was suggested on a forum and we recommend you do this, along with several additional steps.
- First of all, we will switch on the System Restore utility on your computer. Search for System Restore using the Search button in your Windows 10 or the Start menu. From there, click on Create a restore point.
- A System Properties window will appear and it will display the required settings. Inside this window, open the Protection Settings and make sure that protection is enabled on the system drive.
- If it is disabled, select that disk and click on the Configure button to enable protection. You should also allocate a sufficient amount of disk space for system protection. You can set it to any value you want as long as it’s at least a couple of gigabytes. Click on Apply and OK afterward to apply the settings.
- Now, the system will create a restore point automatically whenever a new program is installed or an important change has occurred on your computer.
After you have enabled it successfully, let’s revert your PC back to the state where the debugger error didn’t occur. Make sure you backup some important documents and apps you have created or installed in the meantime just to be safe.
- Search for System Restore using the Search button next to the Start menu and click on Create a restore point. Inside the System Properties window, click on System Restore.
- Inside the System Restore window, select the option called Choose a different restore point and click the Next button.
- Select a particular restore point you saved before manually. You can also select any restore point available in the list and hit the Next button to proceed with the restoration process. After the process is over, you will be reverted to the state your computer was in at that period in time.
- Now, after the process is over and your computer boots properly, open Windows Media Player and click on the Organize button at the top left part of the window.
- Click on Options and navigate to the Library tab in the Options window. Locate the Retrieve additional information from the Internet option under the Automatic media information updates for files section and check the box next to it. Keep the first radio button checked saying Only add the missing information.
- Check to see if the problem is solved.
Solution 2: Check for Newly Installed Programs
Even though this may sound like a long stretch, there are countless users who have tried out every other method suggested online to see it fail but this method solved the problem in less than five minutes.
You will need to check whether new programs or updates have been installed on your PC, especially programs or tools who have something to do with audio settings. If you find them, uninstall them immediately to solve your problem. You can also try to boot into safe mode where all these applications are disabled to see if the issue goes away.
- First of all, make sure you are logged in with an administrator account as you won’t be able to delete programs using any other account.
- Click on the Start menu and open Control Panel by searching for it. Alternatively, you can click on the gear icon in order to open settings if you are using Windows 10.
- In Control Panel, select to “View as: Category” at the top right corner and click on Uninstall a Program under the Programs section.
- If you are using the Settings app, clicking on Apps should immediately open a list of all installed programs on your PC.
- Locate the Change your view button and set it to Details. Now you can simply click on the Installed On tab in order to sort the programs on your computer by the date they were installed on.
- Locate any programs which may have had something to do with sound, audio, or video or generally any suspicious files. In some cases, it was IDT Audio by Apple or even the Sony PC Companion.
- Click the Uninstall button after selecting the tool you want to uninstall. A message will pop up asking whether you want to confirm your choice. Click Yes.
- Click Finish when the uninstalling process finishes, restart your computer and check to see if the problem is solved.
Solution 3: Disable the Windows Media Player Network Sharing Service
Disabling this service helped several users who were unable to open almost all files of a certain extension such as .wav. This simple fix has really helped them but it may disable some other features of Windows Media Player, which is why the solution is suggested at this spot and not in the beginning.

This fix is somewhat complicated as it spans across many stages but it’s definitely worth noting it down as it can be quite helpful and solve the problem where all other methods fail. Good luck!
First of all, we will need to take ownership of the Windows Media Player folder in Program Files so that we can change the Properties of certain files.

- Optionally, to change the owner of all subfolders and files inside the folder, select the checkbox “Replace owner on sub-containers and objects” in the “Advanced Security Settings” window. Click OK to change the ownership.
After this, we will need to disable and re-enable Windows Media Player from Control Panel which should help solve the problem. Even if it doesn’t there is still the final step of the solution.
- On your keyboard, click the Windows Key + R key combination to open the Run dialog box. Type in “control panel” in the box and click OK.
- Change the view in Control Panel to “View by: Category” and click on Uninstall a program under the Programs section.

Uncheck the box next to it, click OK, and confirm any dialog boxes which might appear. RESTART your computer afterward (important)!
- Right after restarting, navigate back to the same spot and re-enable the Windows Media Player entry. Apply the changes and restart your computer again. Try running the file now. If the error still appears, follow the remainder of the steps.
- Navigate back to the Windows Media Player folder in Program Files depending on your OS’ architecture and look for any files where the Security tab in Properties displays that the file is locked. Unlock it and repeat the process for all locked files. The problem should be gone now.
