Hi, I had such a difficult time trying to resolve this error that I thought I would post the fix for it when I figured it out.
This is not my original solution, I found it while researching but this solved my problem for installing google chrome update.
1. Go to Start > Run
2. In the 'Run' window that appears, enter regedit in the text field and click the OK button.
3. In the 'Registry Editor' window, navigate to HKEY_CURRENT_USER\SOFTWARE\Google\Update\Clients\.
4. Right-click the directory '{430FD4D0-B729-4F61-AA34-91526481799D}.'
5. Select Delete from the menu that appears.
6. Close the 'Registry Editor' window.
7. Try installing the program again.
