I recently installed Acrobat Reader DC and it won't launch.  I'm logged on as Administrator, I click on the icon to launch to program, it asks if I want to allow it to make changes to my computer, I say yes and -- nothing!

What do I need to do to make this work?  A large number of my files are pdf and I need it to work!

Could you please try restarting the computer, launch Reader again and see if application starts.

If it doesn't, try closing process related to Reader in task manager and launch Reader again.

Also, try to right click on a pdf file>select Open with>select Adobe Acrobat Reader DC

Please confirm the version of Reader installed on the machine?

Hi amandas18482035,

Assuming you have Windows OS installed on the computer, try repairing Reader and see if that helps.

Go to Start>Control Panel>select Adobe Acrobat Reader DC>right-click>Change.

Click the radio button "Repair installation ........" if it isn't already>click Next.

Once the Repair is complete, reboot the machine and try launching Reader again.

Which Operating System is installed on the machine?

Keep us posted with the results.

Hi namuwood/amandas18482035,

Sorry for the inconvenience caused.

Please create the following registry and verify:

At the following registry key [HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\DC\Privileged]

create dword bEnableProtectedModeAppContainer and make it value 0

Please relaunch your Reader and verify if its able to launch now.

Confirm to me once you experiment this out.

This is a security preference, so ideally it should be enabled to protect Reader from exploits and vulnerabilities.

If your are able to launch Reader after disabling the registry value, I would like to get to the root cause of this issue after enabling the registry back . It could be due to some configuration in your system or some antivirus software conflicting.

Thanks,

Shakti K

Hi Shakti

Adding that dword set to 0 worked! Only thing, after a few hours, Reader quit again. I found that the dword had been reset to 1. I reset to 0=works again. I had tried every other hint, suggestion, but nothing worked but the dword--for a while. It's easier to reset that than it is to reboot all the time.

Thank you for the tip.

Hi there 

 

We are sorry for the trouble and the delay in response. If the issue still persists, would you mind sharing the version of the Adobe Acrobat Reader DC you are using? To check the version of the application please use the link (https://helpx.adobe.com/acrobat/kb/identify-product-version.html) and make sure you have the latest version 20.006.20042 installed. 

 

If it still doesn't work, please try to repair the installation (For Windows). Go to Help > Repair Installation. 

 

For testing purposes, you may also try to turn off the protected mode. Go to Edit (Windows), Adobe Acrobat Reader DC (Mac) > Preferences > Enhanced Security >  turn off the protected mode and uncheck the enhanced security > Click OK and reboot the application and check.

 

Let us know how it goes.

Hi SEDenton

 

We are sorry to hear that. You may try turning off the security application for testing and see if that is the one causing the issue.

Note: Please turn on the security after testing.

 

If it still doesn't work, please try to create a new test user profile on your computer with full admin rights or enable the root account on Mac (https://support.apple.com/en-us/HT204012) and try using the application there and check.

 

Let us know how it goes.

 

Regards

Amal

I m supporting an issues on Adobe acrobat DC  

The user has installed Creative cloud and Adobe DC is a part of it User wants to merge documents and also user wants to set up Adobe Acrobat DC as the main application to launch PDF files

I have the paid version of Creative cloud 

Acrobat DC was made the default application for PDF files and when we launched the PDF files the option of merging or combining PDF applications is not showing up. Signed out and signed in back into the creative cloud and Adobe Dc is not being a part of this -- why so

Hi, similar thing is happening to me and only in the last few weeks.  I can click to open Adobe Acrobat Reader DC and it looks like it is going to open.. then just doesn't.  No error message or crash.. it just doesn't open.  I tried opening as an administrator and it opens, tells me there is some issue and cannot open in protected mode.. would I like to open in unprotected mode. I say yes.. then asks if I always want to open in unprotected mode, I say yes.. and it opens.  Next time I try to use it.. exact same thing happens.

 

I am a photoshop, lightroom etc. user and have no issuers with my other adobe products but this is rather annoying.

I use windows 10, it has worked fine up until a few weeks ago.  I pay for AVG and have tried to open adobe with AVG on and AVG disabled ... no change.

Help!

Hi Mpatterson

 

We are sorry for the trouble and the experience.

 

Is this a behavior with a particular PDF file or with all the PDFs that you open in Adobe Acrobat Reader DC? Please try to open a different PDF file and check.

 

Are you on a private network or company network?

 

What is the version of the Adobe Acrobat Reader DC you are using? To check the version go to Help > About Adobe Acrobat Reader DC

 

A new version 20.009.20063 is now available for Adobe Acrobat/Reader DC. Please try to update the application to the new version go to Help > Check for Updates and see if that helps.

 

You may also try to repair the installation (For Windows Only) Go to Help > Repair Installation

 

If it still doesn't work

 

Please create a new test user profile in windows with full admin rights and try using the application there and check.

 

Let us know how it goes.

 

Regards

Amal

Hi - I've done the regedit thing as suggested above and still no joy in launching Acrobat Reader. This is the second time I've had this problem - the first time was a couple of weeks ago and i eventually solved it by deleting the program and downloading and installing the latest version. It worked fine for the next couple of weeks and was working up till yesterday. Now the same thing has happened again. As I am using the free version, and use it frequently, I am seriously considering purchasing it, but don't want to outlay any cash if it behaves like this. I will delete and try to download and install the latest version - not the way one wants to update a program (if that is indeed the problem) but the only way to do it if i can't even open the thing.

Hi

After reading this page, I uninstalled and reinstalled but that didn't work. Not having confidence to get into the workings of my computer, I uninstalled then left the machine overnight switcvhed off. Next day a ran a clean up program (AVG in this case) and downloaded the latest version. This worked and (touch wood) is still working. Hope this helps

The app worked well for a few years, on multiple computers, but recently will not open on ONE of 3 computers. I have tried ALL the suggested fixes with no success. Some of the suggested fixes were to "open a different PDF file" but the app will not open ANY PDF file and will not even open from the Windows Start Menu WITHOUT a PDF file.

 

You suggest trying to "RElaunch", but it will not open, period, at all, so there is no "RE".

I have uninstalled and reinstalled multiple times, rebooted the computer multiple times, installed multiple Windows Updates over several months, edited the Registry as suggested. Still nothing.

Do you want to know what FINALLY worked?

I installed an alternative program, Foxit free version, which I had also used many years earlier.

Suddenly Adobe Acrobat Reader DC opened up, all excited to "Welcome"me, and pretended there had never been a problem.

 

Anyone who needs a PDF reader and doesn't have time to solve a problem with Adobe, I can recommend the Foxit Free Reader, https://www.foxitsoftware.com/pdf-reader/. It has many of the same features as Adobe, has been around many years with regular updates, and is favourably reviewed on several reliable "tech" websites. There is an optional free trial of a paid version as well, just take what you want.

This doesn't work for me.  Instead of this, it works only when I uncheck  Enable Enhanced Security from Edit > Preferences > Security (Enhanced) . It doen't sound good but for me it's the only way to start the Reader DC after I reinstalled different versions, I change the compatibility with Win8/7 and  also I changed with regedit but without effect.

Same here... If I run as admin, it asks to allow changes then doesn't start.  If I dont run as admin, it just doesn't run.

Brand new version, just tried re-install today.  Also tried repair, and tried 2 different languages on install.

I can see it appears in task manager twice when I run it, but quickly shuts down.

The .exe file has product version 20.13.20064.405839
