Fix: Google Chrome Doesn’t Work in Windows 10

Windows 10 users sometimes complain about various issues when using Google Chrome. Reportedly, some users said that when they try to open Google Chrome, a “Class not registered” error shows up. But we have a few possible solutions for this problem.

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

How to fix ‘Class not registered’ error in Google Chrome

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

1. Tweak your registry

Perform the following steps in order to solve “Class not registered” Chrome error:

• Before you perform these registry tweaks you should create a system restore point first, just in case
• After that, type regedit in the Search to open the Registry Editor.
• In Registry Editor delete the following two registry keys:

HKLMSoftwareClassesChrome
HKLMSoftwareClassesChromeHTMLopencommandDelegateExecute

• 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 has been re-created. In such a case, you may have to again delete these keys.
• Restart your Windows PC

2. Pin a new 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

If you haven’t updated your Chrome browser in a while, this may explain why you can’t use the browser. Regularly installing the latest software updates is crucial for your browser’s functionality and security.

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

If your DLLs aren’t properly registered, you may encounter various Chrome errors or the browser may become unresponsive. Registering your DLLs all over again should quickly fix this problem.

1. Go to Start > launch Command Prompt as an administrator
2. Enter the following commands: FOR /R C: %G IN (*.dll) DO “%systemroot%system32regsvr32.exe” /s “%G”
