Unable to open PDFs in IE11. Error 0:104.
Posted on 2016-09-08
Been getting an error when trying to open any PDF in browser:
"There is a problem with Adobe Acrobat/Reader. If it is running, please exit and try again. (0:104)
This is the envrionment:
OS: Windows Server 2012 R2 (RDS)
Adobe Version: Running both Adobe Acrobat Standard XI (11.0.07) and Adobe Reader DC (2015.017.20053)
Browser: IE 11 (11.0.9600.18427) and Chrome (PDFs work fine in Chrome)
Steps I have already tried:
- Repair on both Adobe versions
- Complete uninstall and reinstall of Adobe
- Reset IE
- Verified default registry value was correct at HKEY_CLASSES_ROOT\SOFTWARE\Adobe\Acrobat\Exe
- Disabling "Adobe PDF Reader" addon in IE does work, but is not an acceptable solution for us.
