You can delete a registry key by two ways, from the command prompt or the registry editor itself. Let me go for the command prompt trick at first.
Step 1: Press Win key and type ‘cmd’ into the search box and hit Ctrl + Shift + Enter. Press the OK button in the User Control pop up box to provide the administrative privilege.
Step 2: After opening the command prompt, type or paste the following commands one-by-one and hit the Enter key to execute.

A) REG DELETE HKEY_CLASSES_ROOT\Chrome
B) REG DELETE HKLM\Software\Classes\Chrome
C) REG DELETE HKCU\Software\Classes\Chrome
D) REG DELETE HKLM\Software\Classes\ChromeHTML\open\command\DelegateExecute
E) REG DELETE HKCU\Software\Classes\ChromeHTML\open\command\DelegateExecute

Step 3: That’s it. Restart the computer to take the changes in effect.
If you don’t want to consider the command prompt as the area of your comfort, you can go for the registry editor to delete the registry entries. Here is how to delete theme using the registry editor.
Step 1: Press Win key+ R and then type ‘regedit’ into the command field.
Step 2: Once you get into the registry editor, locate the following keys and delete all of them one-by-one.

 HKEY_CLASSES_ROOT\Chrome
 HKLM\Software\Classes\Chrome (all of it)
 HKCU\Software\Classes\Chrome (all of it)
 HKLM\Software\Classes\ChromeHTML\open\command\DelegateExecute
 HKCU\Software\Classes\ChromeHTML\open\command\DelegateExecute

Just make it sure that you deleted all of the above keys.
Step 3: You need to restart the computer to see effect of the changes.
You are done! Open the Chrome browser and look for whether the error is still there.

Launch Google Chrome Directly using a BAT File to Avoid the Class not Registered Error

If the above two solution did not work for you continue the following fix. What we want to do is creating a batch file to open the Google Chrome.
Step 1: Open any test editor, preferably Notepad.
Step 2: Write the following commands into the text file.
start /d "C:\Program Files (x86)\Google\Chrome\Application\" chrome.exe
If you install Chrome in different location than the default one (C:\), change the file path as your current one.

Step 3: Give the file with any name you want and save it. Now, double-click the file whenever you want to open Google Chrome instead of clicking the shortcut created at the time of installation.

Re-register All DLL Files

It is possible that the DLL file can also be a cause of the class not registered error of Google Chrome issue. Re-registering all the DLL files would eliminate the issue.
You can register the DLL files by using the following command in command prompt.
FOR /R C:\ %G IN (*.dll) DO “%systemroot%\system32\regsvr32.exe” /s “%G”
