Method 2: Disable Security Software
You may have installed some third-party software for virus protection. It still does not matter, as Windows 10 itself, in case you are using it, comes with a Windows Defender Security Center.
What this program does, is that it prevents Widevine Content Decryption Module from getting the update. It does not occur because it is a malware or any corrupted program. The main reason lies in the new security feature that has been included by Microsoft. In the latest version of Windows, apps or files getting installed without permission has been prohibited.
So when you try to update the component within Chrome, first you need to turn off real-time protection. It is within Windows Defender Security Center. Or if you are using any other third party antivirus program, disable it before starting the update.
You should note that, after you update the component, re-enable your security software.
Check if you are still getting the error after doing all the above. If the error persists, move to the next method.
Method 3: Full Control to Edit WidevineCdm Folder
Now you can also try changing the permission of the folder which is present on your computer. You need to have sufficient privileges first. Otherwise, Windows User Account Control will not allow you to update the plugin. So what we do, is go to the plugin folder. Here we make sure that your account has full control. Once you ensure this, you can again try updating the plugin using method 1 given above.
Follow the steps given below:
1. At First, press the Windows Key & R simultaneously. This will open the Run dialog box.
2. Then type in “%userprofile%/appdata/local.” Next, press Enter.
3. Afterwards, the required folder will show on the screen.
4. Then navigate to the follow path Google>>Chrome>>User Data.
5. When the new window opens, locate the folder WidevineCdm in the list of folders. After you find it, then right-click on it, and select Properties.
6. Then go to the Security tab. Here you need to make sure that your login user has full access to the folder. Afterwards, you can just check if there is a tick in front of Full control in the properties.
7. In case you see that you do not have full control, follow these steps:
- Select your profile and click on Edit… to modify the setting. There should be a tick under the column of Deny next to Full Control. Uncheck it. This will give your account full access. Click on Apply to save the changes and exit.
- Finally, restart your computer. Try updating your plugin using the first method. Then check if you still get the Widevine Content Decryption Module error.
Method 4: Delete WidevineCdm Folder
