Use this plugin to view / transmit audio and DRM-protected HTML5 audio in Chrome (for example, Netflix). If the browser is outdated or you can not find it, this problem will occur.

In the Chrome browser, type “chrome: // components /” to access:

Using these DRM technologies, content creators and owners can set rules for viewing and copying protected multimedia content.

Chrome and Widevine Content Decryption Module

This is a common bug in Netflix and Amazon Prime Video. Appears when browsers can not find a section or view it as outdated.

# Solution 1: Update the Widevine content decryption module

First of all, you should try to update the add-on and check if it resolves the problem. If you see the error message “Update error” or “Update errors”, you can try other solutions.

To update it, you must do the following:

  1. We use Chrome to update the plugin. Follow the instructions below. Also, start Chrome in control mode. Right-click Chrome and select Run as administrator.
  2. After you open Chrome, type the following address in the address bar and hit Enter: Chrome: // accessories /
  3. Scroll to the bottom of the page until you find an entry called Widevine Content Decryption Module. Click Check for Update (Check for Updates).
  4. Close your browser and restart the computer to see if it resolves the problem.

This allows you to update the Widevine content decryption module and use the Netflix service. Otherwise, you should look for other options, such as: analyzing your computer using a good antivirus program.

# Solution 2: Change the permissions for the Widevine content decryption module

This step requires a little more technical knowledge, but it works out if the first solution does not work.

It works, so you have to check the plug-in permissions to make sure you have full control before trying the first solution again. To get started:

  1. Click Windows + R to start the Run program.
  2. Type “% userprofile% / appdata / local” in the dialog box and press Enter.
  3. Then click the following file path: Google> Chrome> User Data
  4. Now go to the Security tab and check if the user has full access. (Select this option by selecting the “Full Control” box.) If you have full access, it’s normal.
  5. If you do not have full control, you must select your profile, click “Edit” and deselect the box in the “Refuse” column to have full access to your account.
  6. Click Apply to save your changes and exit.
  7. Check if the problem is resolved and you can update the content.

# Solution 3: Delete the plug-in folder and update it

Delete the plug-in folder and update it

If all of the previous solutions do not work, we can try to delete the plug-in folder and install it again using Chrome.

Remember that this method may require administrator privileges. Make sure you are logged in as an administrator.

  1. Click Windows + R to start the Run program.
  2. Type “% userprofile% / appdata / local” in the dialog box and press Enter. It will take you to the desired folder.
  3. Go to the following file path: Google> Chrome> User Data
  4. Locate WidevineCdm in the list of folders, right-click and select “Delete”. Click Windows + S, enter the task manager in the dialog box, right-click the application and select “Run as administrator”.
  5. To stop Chrome activity, right-click on Chrome entries and select End Job.
  6. Now go to method 1 and update the plugin using the steps showed. The section must be updated correctly and Chrome restarted.
  7. Restart your computer and try playing the video. I hope it will resolve the problem.

# Solution 4: Check for antivirus software

Check for antivirus software

Depending on the antivirus used, security software can sometimes cause conflicts with your browser.

Because PC security programs like McAfee, Norton and Kaspersky have significant rights, they can really keep you from updating the plug-in.

You can check the configuration of your program to see if there are any conflicting constraints.

Or you temporarily disable the software or firewall. Try updating the plug-in while virus protection is temporarily disabled. This is a good alternative.

# Solution 5: Reinstall Chrome

 Reinstall Chrome

No one wants to follow this path to a terrible reinstallation of Chrome.

But sometimes reinstallation can solve troublesome problems.

After subtraction, it deletes all sections. This means that the corrupted items receive an update.

Follow the steps that immediately exit to perform a reinstallation.

  1. Use Windows + R to run the Run on your computer.
  2. Enter appwiz.cpl in the dialog box. Opens a window with a list of all installed applications.
  3. Right-click on Google Chrome and choose Uninstall.
  4. After deleting, go to the official Google page and download Chrome.
  5. Run after download and reinstall.
  6. Make sure the problem was resolved by reinstalling the browser.

# Solution 6: Content decryption module of Firefox and Widevine

It is not only included in Chrome but is also used by Firefox. As Mozilla explains on the support page, you can use plugins, such as Microsoft Silverlight or Adobe Flash, to access specific content controlled by DRM.

Many services, namely streaming content providers, change to HTML5 video, which requires DRM technology and another – “Content Decrypting Unit (CDM).”

A Reddit user that transmits Netflix to Firefox often has problems with Widevine CDM.

He said he tried multiple common fixes, including safe operation, enabling and disabling DRM, reinstalling, creating a new profile, and eliminating all viewing data.

In the end, he found a solution that apparently temporarily deleted his HOSTS file from the Windows System32 directory and launched Firefox, which allowed the unit to update and fix the bug.

In particular, the HOSTS file “” is blocked.

After removing Firefox Widevine, DRM could inform this user.
