Getting an error like 0x80040902 when trying to update Chrome? Yeah, been there, frustration. Sometimes Chrome just refuses to update, and it\u2019s not always obvious why. Problems can be caused by flaky internet, corrupted files, or even goofy settings messing with Google\u2019s update system. This guide kicks through some real-world fixes that might actually do the trick. Not everything is foolproof, but these are fixes that\u2019ve worked for others \u2014 including in my own experience with random Windows quirks and Mac hiccups. Once you get this sorted, Chrome should update smoothly, and you won\u2019t keep seeing those annoying error pop-ups. Hopefully, one of these should help quick.<\/p>\n
This one applies if your PC is stuck in some weird compatibility mode settings, especially on older Windows versions. It\u2019s kind of weird, but checking this setting before jumping into other fixes can save some headache.- Find the Chrome shortcut or executable (usually in C:\\Program Files\\Google\\Chrome\\Application<\/strong>) – Right-click and select Properties<\/strong> – Switch to the Compatibility<\/strong> tab – Make sure the box for Run this program in compatibility mode for<\/strong> is unchecked – Hit Apply<\/strong> then OK<\/strong> This helps if Windows is trying to run Chrome in compatibility mode unnecessarily, which can interfere with auto-updates. On some setups this fixes the update, on others it doesn\u2019t, but worth a shot before diving deeper.<\/p>\n If your DNS cache gets corrupted or just plain outdated, Chrome might have trouble reaching the update servers. So, flushing DNS can sometimes fix update snags.- Hit Win + X<\/strong> and select Windows PowerShell (Admin)<\/strong> or Command Prompt (Admin)<\/strong> – Type in: Insidious little cookie or cache corruption can cause Chrome glitches, including update failures. Clearing that junk might straighten things out.- Click the three dots in the top-right corner, then go to Settings<\/strong> – Navigate to Privacy and security<\/strong> > Clear browsing data<\/strong> – Choose All time<\/strong> as the time range, check Cookies and other site data<\/strong> and Cached images and files<\/strong> – Click Clear data<\/strong> After that, restart Chrome and try updating again.<\/p>\n If Chrome or related processes hang around, the update can fail. Killing everything forces a fresh start.- Close Chrome – Press Win + R<\/strong> and type Google\u2019s update system runs as a Windows service, which can get all tangled up. Resetting it can often do the trick: – Open Run<\/strong> with Win + R<\/strong> and type Malicious or bloatware tends to cause chaos. If you\u2019ve got apps like Price Meter, BrowseFox, or random antivirus that\u2019s acting weird, try uninstalling them.- Hit Win + R<\/strong>, type If you\u2019ve tried everything else but Chrome still won\u2019t update, resetting settings can clear out the bugs.- Open Chrome, go to Settings<\/strong> > Advanced<\/strong> – Scroll to Reset and clean up<\/strong> > Restore settings to their original defaults<\/strong> – Confirm with Reset settings<\/strong> This wipes out extensions and custom settings but leaves your bookmarks intact. It often fixes stubborn update errors.<\/p>\n Unstable internet can make it feel like Chrome is just refusing to update. Running the Windows troubleshooter is a quick way to find and fix network glitches.- Go to Settings<\/strong> > Update & Security<\/strong> > Troubleshoot<\/strong> > Additional troubleshooters<\/strong> – Select Internet Connections<\/strong> and click Run the troubleshooter<\/strong> Make sure you\u2019re not using VPNs or firewalls that block the update servers. Sometimes, switching to a different network helps.<\/p>\n Last resort, but ever so satisfying. Scratch Chrome completely and then download a fresh copy.- Uninstall Chrome via Control Panel<\/strong> or Apps & Features<\/strong> – Download the latest version from [Google\u2019s Chrome download page](https:\/\/www.google.com\/intl\/en_us\/chrome\/)<\/strong> – Run the installer and let Chrome install fresh and clean – Launch Chrome and try the update again Be aware, you might lose some settings or history if you don\u2019t sign into Chrome first.<\/p>\n Mac users face similar issues \u2014 sometimes Chrome just refuses to update due to incompatible macOS versions or corrupted app files. If you\u2019re running a newer macOS (say, OS X El Capitan 10.11 or newer), these steps might help: <\/p>\n If some junk apps are lurking in your Applications folder, they might be causing conflicts: – Open Finder<\/strong>, go to Applications<\/strong> – Right-click suspicious apps, then choose Move to Bin<\/strong> or Uninstall<\/strong> – Empty Trash to clean up To uninstall Chrome: – Quit Chrome if it\u2019s open (right-click the icon and select Quit<\/strong>) – Drag Google Chrome.app<\/strong> to Trash – Empty Trash Reinstall from the official [Chrome download page](https:\/\/www.google.com\/intl\/en_us\/chrome\/)<\/strong>, then launch and try updating again.<\/p>\n Sometimes, configuration glitches hidden in NVRAM or cache files cause update issues. Reset your NVRAM: – Shut down Mac, then turn it on and immediately hold Option + Command + P + R<\/strong> for about 20 seconds – Release and let the Mac restart normally Also, clear caches: – Open Finder<\/strong>, then press Shift + Command + G<\/kbd> and go to For mobile, basic restart can solve a lot, but if not, here\u2019s what to do: – Open Settings<\/strong> > Apps & Notifications \/ Applications<\/strong> – Find Google Chrome<\/strong> and select it – Tap Uninstall Updates<\/strong> (on Android) or Offload App<\/strong> (on iPhone) to reset the app\u2019s update status If Chrome is stuck, you might need to clear app cache: – Android: Settings > Apps > Chrome > Storage > Clear Cache – iPhone: Offload the app, then reinstall from the App Store Also, cancelling pending downloads or updating your operating system might fix underlying issues.<\/p>\n Getting Chrome to update smoothly isn\u2019t always straightforward, especially if something\u2019s corrupt or settings are out of whack. These fixes are based on common pain points \u2014 sometimes it\u2019s just a matter of flushing DNS, killing stuck processes, or reinstalling from scratch. For many, the key was resetting update services or clearing cache. Hopefully, one of these pieces works for the next time Chrome misbehaves.<\/p>\nFlush DNS Cache \u2014 Because DNS Can Sometimes Mess with Server Connections<\/h3>\n
ipconfig \/flushdns<\/code> and press Enter<\/strong> – A message should confirm the DNS cache is flushed Now, Chrome also caches DNS info internally. To clear that: – Open Chrome, go to chrome:\/\/net-internals\/#dns<\/strong> – Hit the Clear host cache<\/strong> button See if that kickstarts your update process. Sometimes, it\u2019s just network stuff causing the hiccup.<\/p>\nClear Browsing Data & Cookies \u2014 Because Corrupted Files Can Block Updates<\/h3>\n
