Hello,

Wanted to let you know that I'm seeing this too.

I just mistakenly submitted a duplicate issue here:
https://bugs.chromium.org/p/chromium/issues/detail?id=664266

We're sticking with the previous release for now, hopefully this issue doesn't prevent newer versions from installing over-top of the .99 release!

Also got the same thing in our environment with 54.0.2840.99. 54.0.2840.59 worked fine.

 Issue 664266  has been merged into this issue.

I am also able to reproduce this issue in latest chrome version-54.0.2840.99

1. Downloaded and installed chrome from : 
https://enterprise.google.com/chrome/chrome-browser/
2  Launched successfully.
3. Exited 
4 Tried uninstalling from control panel.

Observed: Was not able to uninstall, see the attachment.

We encountered similar problem in canary, Issue 663703 , hence looping to grt@

This is latest regression since this is working fine with previous Chrome Stable i.e., 54.0.2840.87.

Change log : https://chromium.googlesource.com/chromium/src/+log/54.0.2840.87..54.0.2840.99?pretty=fuller&n=10000 

I don't see any suspected cl  which would have caused this and the behavior is similar across all Windows versions i.e., Windows 7, 10.

Micheal, are you aware of any packaging change on Windows?The bug is reported only in latest stable -  54.0.2840.99.

The only recent change I can think of was the fix for  Issue 658728 , but that landed Oct 26, which was before 54.0.2840.87 on Oct 31, so if it was a problem, I suspect it would have have broken that release too.

Also the  Issue 658728  change would apply to all channels. Are we seeing uninstall problems in any other versions?

From the testing that i have done on all of your recent releases, this is the first time that uninstall has failed.

I am seeing similar error with latest Chrome Beta MSI i.e., 55.0.2883.44 as well.

What about dev? That might help narrowing down exactly when it broke.

Chrome 64bit MSI is failing on all Chrome channels i.e., Stable(54.0.2840.99), Beta(55.0.2883.44) and Dev(	56.0.2914.3), Where in Chrome 32bit msi I am able to uninstall correctly.

Note : There is no way we can uninstall Chrome in this case i.e., from Control panel or CMD line, Since all Chrome versions has this error there is no way we can uninstall this from machines until we fix the issue.

Ugh, I forgot that my change for  Issue 658728  wasn't the last change there, so it didn't actually go into effect until grt made another fix in cl/138164721, which was on 11/4. I now strongly suspect that is the problem, though I have no idea why. I can revert that change, which should unbreak this issue, but will break  Issue 658728  again.

This shouldn't have any impact on future updates based on my testing(grt@ please correct me if I was wrong).

I see the problem. We need to revert the -arch x64 change for now until we can fix things.

I believe that running a fixed MSI without first attempting to uninstall the broken one will succeed and repair the state of the world so that uninstall will once again work. We'll update this issue as we have new info.

Can someone confirm whether this issue is a blocker for Stable AU which is scheduled today(11/11)?

AFAIK this wouldn't block our regular updates, Greg please correct me if I am wrong.

A friendly reminder that M55 Stable is launch is coming soon! Your bug is labelled as Stable ReleaseBlock, pls make sure to land the fix and get it merged into the release branch ASAP so it gets enough baking time in Beta (before Stable promotion). Thank you!

Also due to Thanksgiving holidays in US, please make sure fix is ready and merged to M55 latest by 5:00 PM PT Friday, 11/18/16 (sooner the better).

Regular (non-MSI) installs are unaffected.

grt@, could you please provide an update here as we're getting close to M55 Stable launch?

We've backed off the change that caused this. All currently-building MSIs should be good (although they still look like 32-bit installers as before). I will mark this as fixed since I don't think there's anything that needs to be done before M55 hits stable.

[Auto-generated comment by a script] We noticed that this issue is targeted for M-55; it appears the fix may have landed after branch point, meaning a merge might be required. Please confirm if a merge is required here - if so add Merge-Request-55 label, otherwise remove Merge-TBD label. Thanks.

Checked the issue on Latest Beta# 55.0.2883.52 on Windows 7 / 8.1 & 10 and below are the observations --

Observation 1:
(i) Installed Google Chrome 64-Bit MSI installer and was able to install successfully.
(ii) Un-installed from Control panel and was able to uninstall successfully.

Observation 2:
(i) Installed Google Chrome 64-Bit MSI installer and was able to install successfully.
(ii) Un-installed from Registry Editor and was able to uninstall partially. Chrome was removed from Desktop but Chrome was still seen in Control Panel. Have to remove Google Chrome from control panel by deleting manually.

Note: Same behavior is seen from Chrome 32-Bit MSI Installer.

Please let me know if any more information is required.

Thank You.

By "Un-installed from Registry Editor", do you mean that you manually ran Chrome's setup.exe with --uninstall (and other arguments)? This is expected to leave behind the control panel item since it bypasses Windows Installer. If that's it, then I think we're in good shape. Thanks for the confirmation.

@grt -- Yes, that was what i meant. Google Chrome is left behind in Control Panel when uninstalled from Registry Editor using the arguments.
Please let me know if any more information is required.
Thank You.
