Editing a PDF - Adobe Acrobat has encountered an unknown error.

[#1]

When attempting to edit a PDF in Adobe Acrobat Pro DC, I get the error message 'Adobe Acrobat has encountered an unknown error'. This happens with 90% of my PDFs that I try to open and edit. I have seen a lot of work-arounds, but I am looking for a permanent solution that prevents this from happening.

Hi Torialecia,

We are sorry for the trouble. As described, you are getting the error message: Adobe Acrobat has encountered an unknown error.

Please refer to the similar discussions below and see if that works for you

I have read both of these discussions, and I haven't found a solution from them. I am not going to go through the hassle of saving each file as a PDF, then exporting as PDF, and then going to edit. There should be a solution to this issue that doesn't add extra steps each time i want to edit a PDF.

Hi there,

We are sorry to hear that the issue still persists. What is is the version of the Adobe Acrobat DC installed and the OS?

Please make sure you have the latest version 19.21.20061 installed. Go to help > Check for Updates. You may also download the patch manually using the link: (https://www.adobe.com/devnet-docs/acrobatetk/tools/ReleaseNotesDC/index.html) and see if that works for you.

Also, please share the screenshot of the issue you are experiencing for a better understanding.

Regards

Amal

I am running the most current Adobe Acrobat DC. I have no updates to install. I am running it on Windows 10. 

The screenshot of the issue would say the exact same thing as I put in my original question. "Adobe Acrobat has encountered an unknown error".

Hi Torialecia,

We are sorry to hear that the issue still persists. As you are using the latest version of Adobe Acrobat, would you mind sharing the PDF file which is causing the trouble for further testing? 

Please upload the file on the document cloud (https://documentcloud.adobe.com/link/home/) generate the link and share the link with us.

Dear Amal,

we are not able to add every type of image ( jpeg, tiff, png ) on every type of file pdf. The problem is not the pdf file. The problem is inside Adobe acrobat Pro Dc. I think there is a bug taht needs to be fixed from your side. As is see in the community this problem is widely diffused all over your clients/users. In my case the problem arise recently in the last 2 weeks. Before there was no problem. Maybe the last updates of Adobe Acrobat Pro Dc have generated this type of problem.

[#9]

Hi Contisrl,

We tried to reproduce the issue at our end and it's working fine. 

would you mind sharing the sample PDF file and the image which is causing the trouble so that we can further investigate and get this issue addressed?

Please upload the files on the document cloud (https://documentcloud.adobe.com/link/home/) generate the link and share the link with us.

i have just put two files :

https://documentcloud.adobe.com/link/review?uri=urn%3Aaaid%3Ascds%3AUS%3Adf936b31-2212-4243-aed4-baa...

https://documentcloud.adobe.com/link/track?uri=urn%3Aaaid%3Ascds%3AUS%3Aabc63c82-47bf-47f3-9230-c7b0...

try to add the image inside the pdf file that i have just shared with you.

I repeat you that every time i try to add any type of images i get ALWAYS the same error "unknown error".

Please check this issue. We do not like to pay the rent of your software suite if we still continue to have these problems without receiving a resolution from your side

[#11]

Hi there 

Thanks for sharing the sample files. We tried to add the image to the PDF file that you have provided and its working fine. Please find the file here (https://documentcloud.adobe.com/link/review?uri=urn%3Aaaid%3Ascds%3AUS%3Ab6adb8d4-d59a-40f6-aa52-946...)

As described earlier you have the latest version of the Adobe Acrobat DC. Make sure it's 19.21.20061. Go to Help > Check for Updates. You may also download the patch manually using the link https://www.adobe.com/devnet-docs/acrobatetk/tools/ReleaseNotesDC/index.html

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

If it still doesn't work, please try the following steps

• Remove the application using the Acrobat Cleaner Tool - https://labs.adobe.com/downloads/acrobatcleaner.html
• Reboot the computer
• Reinstall the application using the link - https://helpx.adobe.com/in/download-install/kb/acrobat-downloads.html

Do they give you any solutions, I have the same problem

[#13]

No, I still have no solution. 

[#14]

Hi All 

We are sorry to hear that the issue still persists. 

Please update the application to the new version available version 20.006.20034. Go to Help > Check for Updates.

You may also download the patch manually from the link (https://www.adobe.com/devnet-docs/acrobatetk/tools/ReleaseNotesDC/index.html)

You may also try to convert the JPG into the PDF and then try inserting them into the PDF you want.

Let us know how it goes.

Regards

Amal

[#15]

As I have stated before, I have the most updated version. I have the 20.006.20034 version installed. I understand that Adobe believes converting to JPG and back into PDF is a solution to this issue, however, that is not a solution for me. I CANNOT waste time all day doing this with multiple PDFs. There needs to be a permanent solution for this problem.

[#16]

Hi Amal,

i  confirm you that i have the latest 20.006.20034 version installed. I agree with Torialecia that we can not convert JPG into PDF. We (all the clients) pay to have a good product and to have a proper assistance.

We are not stupid and we do not like to receive always the same reply : have you installed the latest version ? ...

I have tried also to unistall the Adope ProDC with your software and then re-install the program BUT i still receive the same error message.

It is a clear that is a bug on your latest releases of your software. We are sure that you are enough smart and intelligent to solve quickly this problem.

[#17]

Hi All 

We are sorry for the delay in response. 

We have a workaround for this problem. Hopefully, it will work in your scenario.

Print the PDF using "Adobe PDF". Edit this newly created PDF instead of the original one.

Steps:

1. Go to File -> Print. (Ctrl + P)

2. Select "Adobe PDF" as the printer.

3. Click Print. Save to any desired location when prompted.

4. Open the new PDF.

5. Edit.

Let me know if that helps.

Regards

Amal

I am following this thread and I have tried all these options including your work around, same issues persist.  Is it possible an Antivirus issue since you don't see it as a Adobe problem like the rest of us?

[#19]

Hi there

We are sorry to hear that the issue still exists.

Is this a behavior with a particular PDF file or with all the PDFs? Please try with a different PDF file and check. if its a file specific issue please share the file with us for testing.

Regards

Amal

Adobe ...

I too am having this same issue.  It worked on Thursday when I was at work, had Friday off and this morning (Monday) it doesn't work.  I have the latest version of the software according to your "Help / Check for updates" on the program.  I even ran the repair installation and that didn't help.

I followed the two previous threads and the solutions in there are of not help.

What is the solution?  I agree with all the others that flipping back and forth between jpgs and pdfs is NOT the answer.  We pay good money for this and it no longer works.

Thank you.

[#23]

I have the same issue. It happens when I try to edit ANY PDF. I am fully updated to the latest version and tried the workaround. Nothing works. Any solution yet?

[#24]

I am having exactly the same issue on Mac OS 10.15.5  Worked well until today. Other tools seem to work fine.  

[#25]

Hi there

We are sorry to hear that. please try to do 'Save As Adobe PDF' and sasave the file with a different name and see if that makes any difference.

Regards

Amal

Hi i have the same problem.

I tried at many PDF, option to add image (jpeg, png) just dosen't work

What i noticed when "Run as administartor" to option works correctly and without the problem.

In normal work is just not efficent to open each file as Admin, do you now solution for this

[#27]

All,

I am having the exact same issue.  Following this thread I have checked for updates and downloaded the latest from the link above even though the "check for updates" said that my PC had the latest version.  The only thing that is working for me is the "Print to adobe PDF" option which is extremely time consuming when I have to use this feature constantly.  

Adobe, you need to stop placing the blame on updates and your customer.  This is a process that needs debugging on your end.  Please fix this so we can get what we are paying for.

[#28]

Hi there

We are sorry for the trouble. To further investigate the issue would you mind sharing the version of the Adobe Acrobat/Reader DC you are using? Go to Help > About Adobe Acrobat /Reader DC

PLease try to turn off the protected mode for testing. Go to Edit (Windows), Adobe Acrobat/Reader DC (Mac) > preferences > Enhanced Security  > turn off the protected mode and uncheck the enhanced security > click ok

Note: Please turn on the security after testing.

Are you on a Mac or Wndows machine and what is the version of the OS

Please create a new test user profile with full admin rights or enable the root account in Mac and try using the application there and check.

Also please share some sample files so we can test it at our end . please upload the files to the document cloud https://documentcloud.adobe.com/link/home/  , generate the link and share it with us.

If it still doesnt work, please collect the procmon logs https://docs.microsoft.com/en-us/sysinternals/downloads/procmon as describesd and shre them for investigation. download the process monitor tool and run the application then try to reproduce the issue in Acrobat and collect the logs.

Regards

Amal

After complaints from so many users, all Adobe says is "it works fine on our side". Does it mean as long as it works on Adobe's side it does not matter if it works on the users' side? Everything was working fine until the app was updated. Could you just let us download the old version again until you have the bug fixed?????????

[#30]

We had the same problem here. Fortunately we had one working environment. Comparing regkeys showed a difference in a language-key: [HKEY_CURRENT_USER\Software\Adobe\Adobe Acrobat\DC\Language\UseMUI]

In our case bUseMUI was set to 00000001. Changing it to 00000000 was the solution.

The regkey should be as followed:

[HKEY_CURRENT_USER\Software\Adobe\Adobe Acrobat\DC\Language\UseMUI]
"bUseMUI"=dword:00000000

You can also change it at preferences: Preferences, Language, Application Language: set to English

This issue was probably caused during updating from DC15 (Dutch version) to DC20 (English version).

[#31]

I have this issue as well. I am a billing administrator for a law firm and we use an ancient but reliable program called RTG to generate our invoices using different formats.  Adobe allows me to edit one format (Arial 12pt) but not another (Courier New 12pt.) Because the only tangible difference between the formats (that I can tell, any way) is the font, I wonder if it is an issue with fonts? Amal, I would like to send you two different PDFs.

I am using Adobe Acrobat XI Pro, version 11.0.23 installed by our IT administrator.  There are no updates for this, and I do not have the option to request a different version. Ergo, please don't reply with steps to update my version.

[#32]

Same issue here, any workable solution yet besides update and print to pdf?
