Reader DC runs as a Background process

When I double-click a PDF file, Reader DC does not appear to start. Task Manager does not show it in the "Apps" list, but instead shows it twice in the Background processes list. It shows as "Adobe Acrobat Reader DC (32)".  If I click "End task" on either process, both stop.

If I manually start Reader, then Task Manager shows it in the "Apps" list, and when I double-click a PDF file, it opens and displays the document normally.  But if I close Reader, then when I double-click a PDF file, Reader does exactly as first described above.  If I continue to double-click PDF files, 2 processes of Reader start for each file clicked and the processes appear in the "Background processes" list, but Reader doesn't open or display any documents.

I am running Adobe Acrobat Reader DC version 2018.011.20035 on Windows 8.1 Pro 64-bit.

I found another Question on the Forum related to this called "DC Reader only run as a background process", but it is only "Assumed Answered".  I ran all the steps in the assumed answer.  I ran the Adobe Cleaner Tool, restarted the PC, then downloaded and installed the Reader version given above.  The problem still occurs.  I see 1,162 people have viewed that "Assumed Answered" question - has anyone found a solution that works please?

Best regards,

Peter

Hi Peter,

As the application not working properly, try to update the application to the latest patch available.

Refer this link Release Notes | Adobe Acrobat, Reader for more information on updates.

Try once repairing the installation.

Launch the Reader DC and go to Help > Repair Installation.

If the above does not help, try resetting the preferences.

Take help of the steps mentioned here How to reset Acrobat Preference settings to default.

Let us know how it goes.

Regards,

Meenakshi

Hi Meenakshi,

This problem has been present for about six months on my PC. No new patches or versions fix it. The latest patch available is version 2018.011.20035.  That does not fix it.

Repairing the installation does not fix it. Completely uninstalling, then restarting the PC, then fresh installing does not fix it.

Resetting the preferences does not fix it. As I said in my original post, I used Adobe Cleaner Tool, which is better than resetting preferences because it completely deletes all old preferences, does not fix the problem.

Sadly none of your suggestions gave any new information or methods to fix the problem.  Can you please escalate this to the highest level.

Best regards,

Peter

Thanks very much for your reply Meenakshi.

OK, first I uninstalled Reader from my current account.  Then I went to the link you supplied and downloaded "AcroRdrDC1801120035_en_US.exe", which proved to be an exact binary match to the download I had installed and mentioned in my original post, which was also the version I had just uninstalled.

Then I created a new account, called "Testing", and then installed the above downloaded application.  It worked perfectly normally in every respect - and it saves user preferences, something that stopped working when I installed this version of reader under my original account.

When I log back into my original account, Reader exhibits the same problems as before.  As soon as I switch back to the Testing account, it works properly.

So there must be something wrong with my original account.  I guess this is now out of your scope, but how can I fix my account?  It has taken 5 years to get where it is - including thousands of user settings for numerous programs.

Best regards,

Peter

Hi Peter,

Hoping that you have managed to fix the system's user account issue.

When I log back into my original account, Reader exhibits the same problems as before.  As soon as I switch back to the Testing account, it works properly.

When application runs fine in test account, there its clear the problem is with your existing user account. The purpose of creating test account is same, it helps identifying whether application is causing trouble or system itself.

So there must be something wrong with my original account.  I guess this is now out of your scope, but how can I fix my account? 

What best we can suggest is to get in touch with with computer vendor. Because this is something that would be taken care by either Microsoft or local IT technician. You might have made some changes or add-on to your user account, which has started casing trouble,

Thanks,

Akanchha

No, it's not a mysterious user profile error. Acrobat Reader is faulty by not being able to run in administrative mode.

This error comes up if you're logged in with a user having administrative rights and then try to open a pdf file from an elevated application because it will force Acrobat to run in admin mode as well.

You can reproduce it any time by the following ways:

- open an application e.g. Total commander (shareware is available) in elevated mode (run as administrator), navigate to a pdf file and try to open it by pressing Enter

- Just to double check, simply create/modify a shortcut to Acrobat Reader to run in elevated mode (Shortcut > Advanced mode > Run as administrator) and then start it.

Both ways you'll end up with two AcroRd32.exe processes in the background just as the OP described.

Please fix!

I was honestly pumped when I was able to use the Student version of Adobe's products. I got every app in the suite for 20 bucks a month. I started installing them and was so happy and excited to use them....uninstalling everything right now. I can't handle the background processes. My 9700k oc'd to 5.1ghz on all cores runs sooo smooth and responsive...until I installed creative cloud and the apps...now my machine feels like a 10 year old dual core with a virus. Adobe's software runs identically to how malware runs on a computer. It takes up soooo many resources and uses up so much RAM. I'm sorry but the only person that can tell my PC what to do is ME, NOT ADOBE! And 20 bucks a month for adobe's software IS NOT worth a slow laggy PC despite how good any software is. Thank God that there is a lot of competition out there in the video editing arena. Yeah, Adobe is nice cause they sync all their apps together so you can just swap projects from one app to the other but dang...I don't mind the extra steps in other software if I don't have to deal with almost 65% CPU utilization from literally 49 background process at startup...that are all from some form of creative cloud or adobe. ADOBE IS BASICALLY MALWARE
