Google Chrome won't open in Windows 10

Google Chrome is still the most used browser on the Internet, but people are also having problems with it occasionally.

And this Class not registered problem is definitely the annoying one. And in order to solve it, you’ll have to perform a couple of registry tweaks.

After you do so, your Google Chrome browser should work fine on Windows 10.

How can I fix Class not registered error in Google Chrome?

  1. Give a try to Opera
  2. Tweak your registry
  3. Pin a new Chrome icon to Start
  4. Update Chrome
  5. Register DLL files again
  6. Uninstall/ reinstall Chrome

1. Give a try to Opera

give a try to Opera

Chrome’s popularity is unquestionable, yet are you aware of the fact that Opera has features not found in Google’s browser?

That reason only determined countless users to make the switch, not to mention that it’s an incredibly lightweight browser, so opening issues are nothing to worry about.

Opera packs a built-in cryptocurrency wallet for safe online transactions, as well as free built-in VPN, reducing online tracking and guaranteeing anonymity above all.

Opera is incredibly stable, brilliantly offering an enjoyable browsing experience. That’s why it’s a worthy alternative to Chrome.

2. Tweak your registry

try to tweak registry

  1. Before you perform these registry tweaks you should create a system restore point first, just in case
  2. After that, type regedit in the Search to open the Registry Editor.
  3. In Registry Editor delete the following two registry keys:
    • HKLMSoftwareClassesChrome
    • HKLMSoftwareClassesChromeHTMLopencommandDelegateExecute
  4. When you delete the registry keys that enable DelegateExecute, they disable Chrome’s AppID. But the problem is that when Chrome updates itself again, you may find that these keys have been re-created. In such a case, you may have to again delete these keys.
  5. Restart your Windows PC.

Perform the above steps in order to solve Class not registered Chrome error.

2. Pin a new Chrome icon to Start

pin Chrome icon to Start

If this doesn’t work, delete the start menu Chrome shortcut and navigate to the following folder: C:UsersusernameAppDataLocalGoogleChromeApplication

Check if chrome.exe works (it should). If it works, pin its shortcut back to the Start Menu, and it should work correctly now.

3. Update Chrome

try to update Chrome

  1. Open Chrome > click on the More icon in the upper right-hand corner.
  2. Select Update Google Chrome, if the option is available.
  3. Launch the browser again and check if it runs properly now.

Note: if you don’t see any option/button to update Chrome, this means that you’re already running the latest version of the browser.

4. Register DLL files again

DLL files

  1. Go to Start > launch Command Prompt as an administrator.
  2. Enter the following command: FOR /R C: %G IN (*.dll) DO “%systemroot%system32regsvr32.exe” /s “%G”
  3. Hit Enter to run the command (ignore any error message that may be occurring during the scan process).
  4. Restart your computer once the scanning process is completed to check if the error persists.

Keep in mind that you might get several error messages while this command is running. After the command is executed, restart your PC and check if the problem is resolved.

5. Uninstall/reinstall Chrome

use Revo Uninstaller

  1. Go to Start> open Apps & Features > located and select Google Chrome.
  2. Click on the Uninstall option.
  3. Use a software leftover remover to make sure that there is no Chrome file or folder left on your device.
  4. Now, go to Google’s official website and install a new version of the browser.

In case you want accuracy, we strongly recommend uninstalling Chrome using a third-party uninstaller. These tools will uninstall Chrome with all its folders.

From all available, we suggest Revo Uninstaller. This is a powerful tool that is extremely user-friendly, as all the products from Revo.
