This is because we did not delete it cleanly when we deleted it. Then Google Chrome is reinstalled. So this problem occurs.

1. Delete the old configuration file, such as C: \ Documents ents and Settings \XXX\ Local Settings \ Application Data \ Google folder (the red part is your computer name)

2. Completely clear the registry, delete chrome-related files, and copy hosts!

3. Restart your computer and install the downloaded offline installation package Chrome!

Note: If the above method is still not feasible.

1. manually delete the C: \ Program Files \ Google folder.

2. Use a third-party tool RegWorkshop to retrieve the keywords "Google" and "Chrome" and delete the associated registry information.

3. Restart your computer and try again.
