After the latest update to chrome canary version 57.0.2975.0 today,canary will not open.All I see is the top bar then it closes.Checking task manager after this event I see two chrome.exe entries are running. Is anyone else having this problem? How will I update canary if I cannot run canary? I am on Windows 7 32bit and have no problems using the latest chrome version.

After delving a little deeper into this problem I found a file called "chrome.7z" Obviously it is a zip file with an option to extract. Anyone think this would solve the problem before I try it? The file is located at "C:\Users\XXX\AppData\Local\Google\Chrome SxS\Application\57.0.2975.0\Installer"
I don't want to screw my system up,so what do you guys think?

Nice

I am having this issue too (Windfows 10 x64) since last updating Canary. I had the same issue some time ago (see https://bugs.chromium.org/p/chromium/issues/detail?id=654193).

@https://bugs.chromium.org/u/1355695261/
To update a misbehaving Canary installation, you need to use standard Chrome or any other browser except Canary, and download the latest available Canary version from http://www.google.com/intl/en/chrome/browser/canary.html

Mind you, the problem might or might not have been fixed…

Same issue.  Win 10 x64. Clicked a link and Canary opened but immediately closed. Retried several times.  I downloaded latest version again and still does it.  Using regular chrome browser to get online. 

Hi crockett

Looks like they messed with the heap shim again :(
As of this post the latest Canary still won't launch after install.

Canary was crashing on one of 2 computers and a crashpad error on the other. Did a full uninstall on both and reinstalled 57.0.2976.0 on both (W10x64 Build 14986).
Canary is working fine on my laptop (reinstall cleared crashpad errors) but crashes immediately on my desktop. The differences are: laptop - 8gb RAM and is AMD processor 2.70 GHz and AMD graphics. The desktop that crashes is: 4 gb RAM and is Pentium dual-core 2.60 GHz with nVidia Geforce 210 graphics.

Errors from desktop:

I am having a similar problem on WIN 7 PRO 64 Bit for a couple of updates now. I have restored back to Version 57.0.2973.0 (Official Build) canary (64-bit) and that works OK. This issue seems very similar to a few past issues on "older" HW - in my case Intel I7 990-X on an X58 chipset. Refer to  Issue 666707  - I thiunk it may be a re-occurrence of this problem.

Happening on Windows 10 x64. I got a similar error message to Comment 9. Adding my debug.log file for clarification and further inspection.

Hey Demented

Looking forwards I suppose I have to start backing up my previous versions in case the current update fails :(

DG...

I have been nailed at least twice in the past with this issue with my "older" (but fast) HW. So as soon as I cannot restart after an update I immediately recover the "Application" sub-directory under the SXS Canary directory from my last - previous 1:00 AM backup - and then make a copy "Application Working". Saves a lot of frustration :).

Hi Demented

Awesome - thanks so much for that :thumbs-up:

Same here, W10 x64 and 57.0.2976.0. 

Same problem

Hi no...

Yes 57.0.2976.0 also fails for me.

Same here, Canary closes within a second of opening. Two chrome.exe processes are orphaned and keep running for about a minute longer before being cleaned up. Chrome Beta still works ok.

Win10 Pro x64 with Canary 57.0.2975.0 and .1 and 57.0.2976.0.

My CPU info:
Intel i7 930
on a X58a chipset
with Nvidia GTX 570

I don't have any backup of a previous version like @Demented did, I only did the User Data folders :-(. Without that is there any way to get back to an earlier Canary build?

 Issue 679146  has been merged into this issue.

Same thing happen on my 32bit Win10 laptop and 64bit Win10 laptop. both are on 57.0.2975.0

Seems to have been corrected with 57.0.2976.3 canary SyzyASan

Hey wgha
Thats a Roger Houston - we have launch ;)

Problem solved with Version 57.0.2976.5 canary (64-bit). Available from http://www.google.com/intl/en/chrome/browser/canary.html

I think this has been resolved. Anyone who's still having trouble, please update to the latest canary.

Yes, resolved in 'Version 57.0.2976.5 (Official Build) canary (64-bit)'
Thanks all at chromium.org!

Validated, returned to work, grateful

Just updated sucessfully to Version 57.0.2978.0 (Official Build) canary (64-bit). All is joy now. Win 7 64 Bit PRO (I7 990-X on X58 chipset).

Thanks.

Thanks for confirming. Carry on! :-)

57.0.2798.0 still won't open for me, starts to load, 4-5 secs., browser closes  . . tried incognito mode, no extensions, same issue. win 7 home 64 bit.

V55 works fine.

Thank you for those. They are both issue 679657, which has been fixed for a few days. If your canary hasn't auto-updated, please re-install from https://www.google.com/chrome/browser/canary.html?platform=win64 (no need to uninstall first).
