Acrobat Reader Cannot open in Protected Mode due to an incompatibility with your system configuration. Would you like to open Adobe Acrobat Reader DC with Protected Mode disabled?
Open with Protected Mode disabled
Always open with Protected Mode disabled
Do not open with Protected Mode disabled

When I choose the first two options it shows me "Acrobat failed to load its Core DLL",

and when I choose the third option then nothing happens. I have also followed instructions in the below link but it doesn't work.

Resolve the Acrobat Failed To Load Core DLL error when launching Reader

I install it and uninstalled it many times but still doesn't work.

I am using Windows 8.

So please somebody help me.

My English is not good so forgive me for my mistakes.

Hello Fayyyaz,

We're sorry for the trouble you had and for the delayed response, please reboot the machine once and then use Acrobat cleaner tool to remove installed Adobe Reader and any previously installed, corrupt and conflicting installation files(if any) Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs

Reboot the machine again and download Adobe Reader's setup file from the URL  ftp://ftp.adobe.com/pub/adobe/reader/win/AcrobatDC/1900820081/

Download the setup file AcroRdrDC1900820081_en_US.exe, once it's downloaded, right click on it and choose ‘properties’.

Click on the ‘compatibility’ tab and check the box ‘Run this program in compatibility mode for’ and select Windows 7/XP operating system from the drop down menu and proceed with the installation.

Once this is done, restart the computer and locate Adobe Reader's icon and right-click and choose 'Run as Administrator'.

Check the functionality of Adobe Reader. If the issue persists, please create a test user profile with full admin rights and install Adobe Reader from the FTP URL and check.

Let us know how it goes and share your observation.

Hi.i've transfered my system (Win 10 Home) from hdd to ssd and have same problem. I was doing everything / reinstaling reader, clearing register and nothing worked. BUT... I've just solve that problem. just "open as administrator" 🙂 worked perfect 😄 You may change in proporties of arcobatreader exe to always open as admin.
