CoreSync.exe is causing Explorer.exe to crash in Windows 10

[MrGlennJones]

Since the latest creative cloud update, I've been experiencing explorer.exe crashing and reloading in windows 10, after investigation i have seen large cpu spikes and using proccess monitor seen the process coresync.exe just before explorer crashed.

Disabling the creative cloud app and CoreSync.exe has resolved my issue.

reset the cc desktop app by making sure it's in the foreground, then press:

Win: Ctrl + Alt + R
Mac: Cmd + Opt + R


if that fails, repair per https://helpx.adobe.com/download-install/kb/creative-cloud-install-stuck.html


if that fails, uninstall using the correct uninstaller from https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html#sa_src=web-mes... and then reinstall using*


if that fails, do a clean cc install carefully following each applicable step:

uninstall every cc app including preferences per https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html

then uninstall the cc desktop app, again using the correct uninstaller per https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html#sa_src=web-mes...

clean your computer of cc files per http://www.adobe.com/support/contact/cscleanertool.html

check for, and if available, update your os

if windows is your os, repair all ms visual c++ versions that can be repaired (use google if you don't know how to do this)

if windows is your os update your ms visual c++, if it can be updated (use google if you don't know how to do this)

restart your computer (don't skip this)

reinstall the cc desktop app using the "alternative download links" at the bottom of the page at https://helpx.adobe.com/download-install/kb/creative-cloud-desktop-app-download.html

use the desktop app to install your cc programs/trials

NOTE: win 11 users that have trouble with the latest win 10 installer often have success with the older win 10 installer.

Many thanks for taking the time to reply to this, unfortunately after performing your suggestions, the problem still persists...

I'll be looking into this further and will need to create some crash dumps to analyse once I finish some curent important projects.

For the moment, I only start the creative cloud processes when using adobe apps, as the cloud library content becomes becomes unavailable otherwise. bit frustrating but the crashes are becoming annoying.

@MrGlennJones 

did you update and repair all your visual c++ versions?

[MrGlennJones]

yes all the ones that i can

[kglad]

so, everything that allowed you to select "change", you selected and clicked repair?

[MrGlennJones]

yes, correct.

[kglad]

ouch.  you try adobe support via chat.  they may be able to check your computer and find the cause.

there are 2 ways to contact adobe; chat and twitter:

chat:
use a browser that allows popups and cookies
and click here, https://helpx.adobe.com/contact.html?rghtup=autoOpen
in the chat field (lower right), type AGENT
be patient, it can take quite a while to reach a human.

twitter:
tweet @AdobeCare

p.s. if you're contacted by anyone (via email or private message), it's much more likely to be a scammer than an adobe representative. ie, double check for an employee badge if contacted in the forums and look for an adobe.com domain in the email address if you click reply to an email. then check again and be very suspicious. any other method of contacting (or offering to contact you) is almost certainly a scam, https://community.adobe.com/t5/using-the-community-discussions/staying-safe-in-the-adobe-support-com...

[MrGlennJones]

thanks for helping, I'll look into it further.

you're welcome. update this thread, if you have time and get more help.

[MrGlennJones]

I found these other threads, with the same issue which you've seen of course...

My solution is to kill the coresync.exe process in task manager, then everything is rosie 🙂

Hi @MrGlennJones,

We're sorry to hear about this. Please let us know if you have recently installed any software on your device. Make sure your Windows operating system is up to date. Also, try performing a full system scan to ensure your system is free from malicious programs.

Thanks for your patience.

[MrGlennJones]

not that im aware of, im still looking into it... for now im disabling the CC app to maintain stability

[MrGlennJones]

I still can't find a solution to this, having to kill all the Adobe processes is becoming tiresome... 😕

also in the creative cloud app, switching off "sync creative cloud files in the background after quitting" doesnt work.... the coresync process stays open and is constantly crashing explorer.exe

remove your browser add-ons (either selectively to pinpoint the problem, or not ) and retry.
