What is the "Adobe CEP HTML Engine"? It`s using too much from my processor.

[guilherme_laars]

I`m trying out Photoshop CC from the past 10 days. It`s going well, but now, every time I open it, the workspace blinks white and the processor runs slow, avoiding the actual use of Photoshop.

In the Task Manager I've identified this 4 Processes called: "Adobe CEP HTML Engine", using lots of processors %. Closing them, I got back to Photoshop and it`s possible to work again, till the next file.

Every time I start PS or leave the workspace with no opened file, it starts all over again. Then I have to go back to Task Manager and finish the same processes again.

How to fix it for good? Is it related to Behance?

I`m using a Dell notebook, Core I7, 8Gb RAM, Win10 64.

Cheers.

Here is a solution for win users (maybe have to repeat if the problem comes back) (thanks to Manish)

End all Adobe processes including Creative Cloud (all sub processes), Core Sync, CCLibrary, Adobe Desktop services, Adobe UpdateNotifier, Adobe IPCBroker processes from task manager.

When its done (be sure, no other adobe process left i didnt mentioned, like acrobat updater, AGS etc)

Go to

c:\Users\<user_name>\AppData\Local\Adobe\OOBE\
(or type %LocalAppdata% in run window (Win btn+R))

************** DELETE Opm.db ******************

should work, have fun with your "liberated" CPU time

here, all the CEP HTML processes using 0,1-0,2% now (better than 9-10%), but yeah, still here.. and they are watching me... wáááááááááááá...

i "fixed" it now for indesign by throwing out the CepHtmlEngine.exe out of its folder onto the desktop.

Hi all,

Until we have a fix in the Creative Cloud desktop app, I suggest that you use the solution in this document https://helpx.adobe.com/x-productkb/global/high_cpu_usage_cephtmlengine.html

Thanks,

Preran

[Shopology]

This fix worked for me!

[cmyck]

Preran Right... some major versions later it STILL is an issue.

I just installed 2017.0.1 on my Mac and ran into the exact same issue.

What a bloody drag, really. Cost me 3 hours of trouble shooting.

This did help: High CPU usage due to CEPHtmlEngine

But Photoshop is still an incredibly inefficient CPU and resources hog. And it seems to get worse with every major update.

Adobe should switch from their add-useless-features-philosophy to a make-it-bugfree-and-efficient-philosophy.

Hi There,

I disabled the libraries panel in both Photoshop and After Effects and that seems to fix the issue for them,

however they still appear when using Illustrator and Indesign. Closing the Libraries Panels in those apps doesn't help

get rid of CEPhtml for me. Are there any other panels in Illustrator and Indesign that use this function?

Thanks

Stefan

Thank you!!!

[The_Badger]

I like the end to the page you suggest is a solution.

"Adobe engineering is aware of the issue and plans to address it in a future update."

Well it's almost 2019? When exactly are you going to move out of the planning stage.

My brand computer with a clean new install of CC2019 still has this issue!!!!

[valentinb50846113]

I think that work around help me solve my performance problems

Thanks

So we are forced to pay for a subscription model which can be updated at any time and yet the fix is to update ourselves? Testing Adobe.... testing

[christopherj66810397]

Any update on this Adobe?

We're also struggling with this on our Win 7 PC's ... you've released numerous updates since this thread started but still not fixed this issue!

[bradthomasmenulog]

+1 for annoying PS CC 2014 errors (yes, I rolled back to see whether it was unique to PS 2015... seems it's not.)

Fix plez?

[anenglishman]

Has this been fixed with the latest updated (17.03.2016)? If not do I have to run the fix again (High CPU usage due to CEPHtmlEngine) after the update?

I would be if this was FIXED before 2017?.........

I have just come across this issue myself. I am using the latest version of Adobe Photoshop (2015.1.2/20160113.r.355 x64), which I installed 2 weeks ago. I noticed a considerable amount of CPU usage on my laptop while running the program. At first, I checked out the Task Manager, and noticed several processes called "Adobe CEP HTML Engine (32 bit)", one of which was using about 35% CPU usage. I ended the task, and saw the Libraries tab in Photoshop briefly disappear and then re-appear. However, the process came back, and continued to consume the same amount of CPU usage.

Upon reading a link with possible solutions as mentioned by Preran before, the problem appears to have resolved itself once I created 2 new folders under C:\Users\username\AppData\Local\Adobe; one with the name "Creative Cloud Libraries", the other in the new folder "Creative Cloud Libraries" called "Logs". Immediately after I had done that, a log file by the name of "CC Panel Library PHXS 16.1.2.log" appeared in the Logs folder, and the CPU usage on the process dropped down to 0%.

The log file has the following inside:

Sat Mar 19 2016 12:10:45 GMT+1030 (Cen. Australia Daylight Time) {"errno":-4058,"code":"ENOENT","syscall":"open","path":"C:\\Users\\username\\AppData\\Local\\Adobe\\Creative Cloud Libraries\\Logs\\CC Library Panel PHXS 16.1.2.log"}

Just updated today to 2015.2 7884 Build which seems to have sorted the high CPU use of the "Adobe CEP HTML Engine".

(Tested with Illustrator, Photoshop, Illustrator so far).

[kaske]

None of the latest updates worked for me so I applied the workaround from Adobe: https://helpx.adobe.com/x-productkb/global/high_cpu_usage_cephtmlengine.html. I still see multiple CEPHtmlEngine Helper files opening and closing via monitor (Mac El Capitan), but it seems they are affecting the processor much less, but I still haven’t started working full throttle so I’ll recheck.

[anenglishman]

I still have to use the adobe fix to get around the problem. Any news yet on a solution Adobe? More information needed!!!!

I pay a lot to have adobe software. This problem has been around for months.

[sambroadleaf]

trash problem from trash company

the solution is very simple

REMOVE THE CEP folder, done.

Just delete the thing, thats it.

[jaaao]

Was online with adobe support and they fixed it.

this is how:

Msconfig > Services > hide all microsoft services > deactivate all service > restart

[tonyreidsma]

I can't believe we're still dealing with this garbage!

Adobe, seriously get it together!!

I just updated and I'm getting this again!

I went in to each app, show contents, and I removed each CEPHtmlEngine thing and it doesn't do it anymore.

As soon as I'm able I'm dumping ADOBE and throwing a party!

[cmyck]

tonyreidsma​ Party? Hell ya, I allready ditched Illustrator for Sketch.

[1356436456746545647]

I'm having the issue now myself, I had to recently reinstall photoshop and now it's made the entire thing unusable due to it which I don't even think it appeared at all in task manager before now, it's not working with either photoshop 14 or 15, have'nt tried the newest one yet.

Deleting the file works to get rid of the processes but I lose my magicpicker extension because of it, which i've been using for a long time so it's not the issue.

[sambroadleaf]

iirc i completely shut down CreativeVirus(the adobe launcher) with PS, and then went into some CEP folder on c:/ and just wiped everything that has CEP in it.

Its on windows tho i dunno if you can do the same on mac.

[totolelehero]

I also ditched the Adobe desktop services...well copied it...as well as the cephtmlengine...it got my computer moving...
Stopped nodejs from accessive server side stuff from adobe

We need more women in software Development.

[VPinho]

Oh, i got it! I deleted the freakin file "CEPHtmlEngine.exe" and now my Premiere Pro CC 2015.2 run very very well because there is no High CPU usage of HTML Engine!

So, just go to "C:\Program Files\Adobe\Adobe Premiere Pro CC 2015\CEPHtmlEngine", backup the "CEPHtmlEngine.exe" (compress it using WinRar or something like that) and then delete this dump file using Shift key + Delete key!
