Hi. i'm unable to reproduce this with today's canary. Would you please try running the installer from https://www.google.com/chrome/browser/canary.html?platform=win64? No need to uninstall your current version first -- the installer should update and repair it. Please let me know how it goes.

Unfortunately, I can't seem to re-install Canary either. When I launch the installer, I get the following error message: 

"Another operation on Google Chrome is in progress. Please try again later."

I've tried killing all existing Chrome processes, restarting, etc. So far, no luck.

I can confirm that I'm having a similar issue.

At first I couldn't launch Canary, version 60.0.3087.0, getting the same error message as reported in this bug. Uninstaller could not be started either.

Trying the Canary installer gave me the same "Another operation on Google Chrome is in progress. Please try again later" error message.

After the installer failed, there were three chrome installer tasks in task scheduler. I tried stopping those tasks, but there is one that I can't stop from task manager. However, after stopping all except that one task, the installer worked and I was able to Launch Canary version 60.0.3090.0.

But, I can still see that one installer task still there in task manager (I haven't rebooted the machine).

+fdoray: That message corresponds to IDS_INSTALL_SINGLETON_ACQUISITION_FAILED, which generally means that another instance of setup.exe was wedged. Is there any other reason that could happen?

Full memory dumps of the hung processes might help pinpoint the uninstall/reinstall problem, which is a different bug from the sxs issue. Meh.

Here's the memory dump from Google Installer when it fails to install.

Thanks. By killing chrome processes as they spawn, I was able to uninstall Canary. 

When I reinstall, it works fine. Thanks for the help!
