Can you explain a bit more?
thanks.

Hi. Did you install from https://www.google.com/chrome? This is a 64-bit Win7 machine?

The error you're getting typically means that there is something wrong with Google Update's COM registration on the machine. This is highly unexpected for a fresh install. Have you made any other customizations to this machine?

Thanks for your help in tracking down the problem here.

yes.
I did install from here https://www.google.com/chrome/browser/desktop/index.html

yes.
win 7 64 bit.

No customizations.
Thank you.

is there a way to manually run the recovery component?

Perhaps full uninstall of Chrome, then run the Chrome Cleanup Tool:

https://www.google.com/chrome/cleanup-tool/

Then reinstall Chrome. See if that helps?

Comment#5.
Tried already.
No use.
Thanks.

0x800700c1 is ERROR_BAD_EXE_FORMAT do you know why this might happen, ganesh?

Paraphrasing from https://bugs.chromium.org/p/chromium/issues/detail?id=442936:

The problem could be that Google Update's psmachine_64.dll isn't registered for some reason. HKCR\CLSID\{003EB908-0B86-44F8-86F0-B19A7022449C} is not found, so it falls back to the 32-bit version (HKCR\Wow6432Node\CLSID\{003EB908-0B86-44F8-86F0-B19A7022449C}), which naturally will result in a ERROR_BAD_EXE_FORMAT error since a 32-bit DLL can't be loaded into a 64-bit process.

A possible theory based on a comment in https://bugs.chromium.org/p/chromium/issues/detail?id=442936: could it be that Chrome thinks it is installed per-user, and therefore tries to load the proxy from psuser_64.dll?

Update for my case:

I have validated that following the steps as outlined in #26, I was able to then find the registry key found as outlined in #43. Folling the suggestion of hayto to change the registry key from psuser_64.dll to psmachine_64.dll results in Chrome now showing "Google Chrome is up to date".

I'll update the ticket if the error comes back.

Tried from https://bugs.chromium.org/p/chromium/issues/detail?id=442936

Still no use......

I change the google\update folder from program files to program files (x86) and run googleupdate.exe /regserver.

Now the problem changed to 0x80040111.

Thanks.

So originally, the google\update folder was under Program Files, not program files (x86)? 

re: #14
yes.

but then now I change back HKCR\CLSID\{003EB908-0B86-44F8-86F0-B19A7022449C} to link with program files and psmachine_64.dll, 0x80040111 occurs instead of 0x80070001.

Actually should I change the location of registry first or run googleupdate.exe /regserver first?

Just run GoogleUpdate.exe /regserver from an elevated cmd prompt. Do not change anything manually using regedit. Thank you.

just wonder if there is any way to uninstall chrome thoroughly......including registry and everything etc.....
thanks.

You should be able to uninstall Chrome via Add/Remove programs in Control Panel. This should remove everything of relevance.

Tried re-installation.

No difference.
Still 0x80040111 error occurs.

error 0x80040111 still exists...

 Issue 719294  has been merged into this issue.

Could you please try the following?
* Uninstall Chrome.
* Reinstall Chrome by downloading from this link:
https://dl.google.com/tag/s/appguid%3D%7B8A69D345-D564-463C-AFF1-A69D9E530F96%7D%26iid%3D%7B482EEE34-EC25-4381-BD5D-B76A813DB502%7D%26lang%3Den%26browser%3D4%26usagestats%3D0%26appname%3DGoogle%2520Chrome%26needsadmin%3Dfalse%26ap%3Dx64-stable-statsdef_1%26installdataindex%3Ddefaultbrowser/update2/installers/ChromeSetup.exe

The installer at this link installs Chrome per-user. It would be interesting to see if Chrome works as a per-user install for you. Thank you.

is that URL for Canary?

No, the URL is for stable Chrome.

OK cannot use. My issue is with Canary. Gives me CANNOT UPDATE error, has for months.

canary installs are always per-user

Comment #22 gan...@chromium.org

Following your instruction,

Install Chrome using this link:
https://dl.google.com/tag/s/appguid%3D%7B8A69D345-D564-463C-AFF1-A69D9E530F96%7D%26iid%3D%7B482EEE34-EC25-4381-BD5D-B76A813DB502%7D%26lang%3Den%26browser%3D4%26usagestats%3D0%26appname%3DGoogle%2520Chrome%26needsadmin%3Dfalse%26ap%3Dx64-stable-statsdef_1%26installdataindex%3Ddefaultbrowser/update2/installers/ChromeSetup.exe

The problem is now solved!
Now it can show your google chrome is up to date now.

Thank you very much!!!!!

By the way, how to find this link?
If I have the same problem later on, where can I find the per user-chrome?
Can't I download chrome from google directly?
Thanks.

Downloading from www.chrome.com will work. When running the install, dismissing the initial UAC will cause GoogleUpdate to prompt if you would like a user install, and on the user saying Yes, will install per-user.

As per comment #29, closing this issue as Wontfix and please feel free to raise a new issue if you face any issues in latest chrome channels.

Thanks!

Chrome Canary still cannot update once installed.
