I am running the latest versions of Indesign, Photoshop and Illustrator at the same time. I am having a lot of issues with the CPU running very high and on the task manager I see Adobe CEPHtmlEngine.

 

Please advise how I can fix this issue.

 

Thank you.

I also use my CC license on another PC which has Windows 10 and I seem to be getting same problem.

See screenshot below:

Do you think that upgrading is really going to help the issue?

This doesn't help with InDesign2020 (15.0.2). I've followed the directions in the link and it's the same issue: extremely high CPU usage and battery drain. 

Any help would be appreciated.  

Thanks!

I have the exact same problem. But this doesn't help for me... I tried to do both actions, but the second sugestion doesn't exist😅😅. It says to go to this folder: 

/Applications/Adobe Photoshop CC 2015/Adobe Photoshop CC 2015.app/Contents/Required/CEP/extensions/com.adobe.DesignLibraryPanel.html/

I changed it to:

/Applications/Adobe Photoshop 2020/Adobe Photoshop 2020.app/Contents/Required/CEP/extensions/com.adobe.DesignLibraryPanel.html/

 

But in the 'Required' folder isn't a folder called CEP, so I cant go to /CEP/extensions/com.adobe.DesignLibraryPanel.html/

 

Any help would be really appreciated!

It doens't apply to Adobe 2020. These folder do not exist and I have tried everyway to locate the file but failed. Could you provide an updated solution? This bug is really annoying and drains my laptop. Thank you very much!

Hi,

 

For adobe 2020, you could try searching in
C:\Program Files\Adobe\Adobe Illustrator 2020\Support Files\Required\CEP\extensions\com.adobe.DesignLibraries.angular\

It's now September 2020 and this issue still remains. Constantly not responding in Activity Monitor. In the link you provide as a fix there is no mention of After Effects. at the bottom of the page this is stated 

Note:

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

Please note the date – Last Published: 17 April 2019. That's a year and a half ago. In that 18 months I have paid Adobe £1,062. There are constat issues. I'm sure the Adobe community would greatly apreciate a year where no new features were added to the suite, but the software was made as close to 100% reliable as possible on Windows and macOS. Check YouTube for peoples frustrations with Premier being so unreliable. This is no joke, people are tired of the bugs. Davinci Resolve and Fusion are powerful free software alternatives, the only thing holding me back is the downtime I would need to learn Fusion. There's only so much of the buggy software I can take.

CC2020 better be ready for macOS 11 as I will be upgrading to make full use of Redshift for Cinema 4D, I'm sure Blackmagic will be ready.

Utterly disgusting, providing links for fixes to cc2015, on top of the money paid every month, the hours ive lost in trying to fix this stupidity and the lost work hours trying to do things that take 10x as long or dont get done, ive started using free online browser apps which do the little things but what a joke that i have to. Feel like invoicing Adobe for my lost work hours but i can imagine that would not get paid, not get a reply, or a post to a fix from 2015 just to infuriate me more.

cc2020 now cc2021 is even worse for illustrator, unuseable.

Posting here as this is an issue for me as well. Running the latest Creative Suite on a brand new Macbook Pro with 32GB of RAM... never had the fan come on so much it's bizarre. C'mon Adobe, get on it.

My MacBook Pro (2017, but with new battery) is strugling with the CPU, the fan going off the rails. This is so anoying. The Activity Monitor sais it is CEPHtmlEngine (1168) that is using all the CPU, and I can see after googeling it that it is a common error that has lasted a long time. I tried to look at the "fix" you provided, but the correct file name is not in the folder (sollution 1) and in the file I should download to replace the files in sollution 2 I can not find the similar named files. Also I run on CC2020-programs as one person points out here, not CC2015 that is described in the fix. I´m running all the latest programs on CC.

3,1 GHz Intel Core i7

16 GB 2133 MHz LPDDR3

 

What are you doing to address this issue? For people like me that are not too technical this is far to advanced to be dealing with, I can not risk doing something wrong and suddenly loosing my access to the programs etc.

I'm having the same problem and have almost the same memory/processor spec as your machine, although mine is little older. I'm running 16GB RAM, 2.9GHz Intel I7.

 

I often see this when I look in the activity monitor:

Hello,

I also have the same issue, since last February (cannot remember exactly when)

I am running a i7 Dell Precision 5820 machine with 48 GB RAM and Windows 10, latest version.

The Video card is a Nvidia Quadro P2000, latest drivers

When Opening Photoshop, mouse flickers and I cannot access the menu.

Opened 3 tickets but no solutions other than "wait for update" (NVidia it seems)

I am using a workaround: rename the file C:\Program Files\Adobe\Adobe Photoshop 2020\Required\CEP\CEPHtmlEngine\CEPHtmlEngine.exe, but you will have to repeat it at next Photoshop update.

I installed the previous version of InDesign (15.1.1) and no longer have the high CPU usage or crazy fan issue. The CEPHtmlEngine CPU usage is staying around 2.2%.

Hello community,

I am also struggling with an overheated CPU, draining my battery down to 2% in power plugg state, when working in InDesign. Already tried the reccomended instructions but unfortunately no improvement.

MacBook Pro, macOS Catalina 10.15.5.

Hope for a speedy fix soon?

Hi everyone!

I have the same issue with InDesing 2020 on a new Mac I've just bought.

MacBook Pro, macOS Catalina 10.15.6.

I thought the problem was on the Mac, but I've checked with Apple support and it's not th case.

 

There is no folder to follow the instructions provided in the help. Does anyone succeeded in solving this?

It is really annoying and makes it almost impossible to work smoothly, while I need to work on InDesing for several hours a day. This is really disappointing.

I've never had this problem with previous versions of InDesign installed on an older Mac...

 

Thank you very much for any help!

All the best, Laura

Hi KiddoMac, thanks for your feedback! What do you mean for manual bugfix? Yesterday I asked support from Adobe and did some remote checks. Today I'm testing if the problem is solved or not. I'll surely let you know soon how it goes!
