My guess was that at some point, permissions on the Google Chrome installation directory got hosed, which prevented any updates or an uninstall from taking place. This is certainly strange indeed, considering the Administrator user should have access to uninstall anything.
As Scott suggested, Chrome would not update and would not uninstall under his user account, so I enabled the Administrator account using an elevated command prompt, then logged in as the Administrator and tried to uninstall it unfortunately I received the same error message 'You do not have sufficient access to uninstall chrome'. I asked Scott if he would like me to connect to his system for a closer look, and he agreed. What is going on here? I would like to hire you to fix this vexing issue because my business relies on it. I tried uninstalling Chrome but Windows 10 says 'You do not have sufficient access to uninstall Chrome'. (error code 7: 0x80040902: 106 - system level).' I have no idea what that means. Sometimes I get an error message that says: 'An error occurred while checking for updates: The installer encountered error 106. If I click Help -> About, it says it's up to date, but it's not. Dennis, I have not been able to update Google Chrome for about a year.
