Acrobat Reader: "An internal error occurred" popup after installing Windows 10 - Chrome also fails to launch

[Guest]

Since installing Windows 10 this month when I try to launch Adobe Acrobat Reader the only response I get is a pop up, “An internal error occurred ”. I uninstalled then re-installed. Same problem. I tried the Adobe cleaner, acrobat_ittools_cleaner_p2_061713.exe, followed by re-installing the program. Same problem. I can not find any current solutions to this problem posted on the web. Can you help me? Thanks much,

PS Chrome no longer works either. Tried to uninstall Chrome but no luck. My PC says it is 'running'.

Hi bobl6606355,

I am not sure about Google Chrome, however for Acrobat Reader DC try this :-

Go to the registry and find this key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\DC\FeatureLockDown

Create a new REG_DWORD

Value Name :-

bProtectedMode

Value Data :-

0

Let me know if it works.

Regards,

Aadesh

Hi Aadesh,

Followed your instructions as shown in this snip. Still get the error popup. Do I need to delete the default file shown here?

Thanks for your help.

Hi Aadesh,

I have uncovered an important clue that may suggest the source of this problem. When I right-click the Acrobat Reader DC icon and select “Open as administrator”, the reader program launches. Does this clue suggest a solution that you can recommend to me?

Thanks much,

Bob

Hi bobl6606355,

It seems to be the issue with permissions.

Please unhide all files & folders on your system.

Navigate to [drive]\Users\[user_name]\AppData\Roaming\Adobe\  & then provide all the permissions to the complete folder.

How to give permissions on a folder

- Right click -> Properties -> Security -> Advanced -> Owner -> Select the account

Let me know if it resolves the issue.

Regards,
Aadesh

It doesn't work for me

[tablo27]

thx,

this item in register helps, but I must start AR thru "run as administrator"

I'm satisfied

I can give you a script so that you don't have to modify the registry manually.  But I need to know your installed Reader DC version.

[Guest]

Hi pwillener. I am thankful for your offer to help me. I downloaded the most recent version from the Adobe website. Being as it will not launch, I do not know how to determine the version number. THANKS VERY MUCH INDEED. Bob

I would like to get assistance on this issue since I've been having the same error message and I already tried every solution exposed here, except for the registry one, since I couldn't find the folder.

I would very much appreciate your help.

I did encounter this error after the update to the version 22.
Bug : When using the comments options, or clicking on "file", the system show 8-10 pop-up of the error, stacked on eachother. Adobe crash and I have to reopen it.

I couldn't find any folder who have a difference in access right. Reinstalling Adobe did nothing at all.

Launching it with admin right make it works. 
Final solution : Delete and recreate the profile of the user. After that, everything works like a charm. 
I hope it will help someone.

Are you talking about the PC user profile or something associated with Adobe?

[taylor315]

"Works like a charm" would be amazing. What does it mean to Delete and recreate the profile of the user?
---

I get "An Internal Error Occurred" repeatedly whenever I try to open or even hover over a PDF. If I try to rename it, it will even make my explorer window briefly say, "Not Responding." It's absolutely infuriating because I'm used to being able to just jump in and out of PDFs like any other program.

This notification acts almost like virus pop-ups in its constant annoyingness where you have to close it and then do something and it pops up again and you close it.

I've tried uninstalling and reinstalling Acrobat, and I've tried various fixes I've seen on this Adobe forum, including having full permissions for all my folders. I'm currently running version 22.0. (I can't remember with which version I started having issues but it started last year sometime.)

Hi,

I've tried the solution proposed by AadeshSingh but it did not work for me.
Any help?

Thanks,

did you manage to resolve the issue?

[gustavos56078190]

I am also encountering the same issue "An internal error occurred", I tried reinstalling and the following instructions "AadeshSingh" without any luck I appreciate some guidance 

[Giovanni22846570mald]

Hi Gustavo,

I've asked our IT service to help. I could see that he reinstalled the software several times but without any success to solve the issue. At the end he manged to really make like a new installation but I could not really understand what he cleaned out from my pc.

[gustavos56078190]

Thank you this is a very strange issue, i could not find any solution so far

I FOUND A SOLUTION.

I had to go C:\Users\[me]\AppData\Local and right click the Adobe folder, click properties and go to security tab. I had a bunch of left-over "Account Unknown" listed besides my three main ones (System, [me], Admin). I deleted all the account unknowns.

That fixed it for me.

[Mark2694669659e7]

had same issue tried the delete unknown and dont have any errors so far looks good
