Bad installation failure error code 0xa0430721 solution

The installation failed because it was not removed cleanly when the file was deleted.

I have tried a method that works.

Steps:

(1) Create a new text document.

(2) Copy the following contents into the document.

Windows Registry Editor Version 5.00

(3) Save the text document as a. reg file and double-click Run.

(4) Restart your computer to install the downloaded offline Chrome installation package.
