Installed Adobe Acrobat Reader DC on a new Microsoft Windows Server 2016 Remote Desktop Services (RDS) session and it fails to open with ‘An internal error occurred.’ message.
Have come across this before and it was a quick registry fix, all we had to do was add in the below –
- Open up Regedit
- Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\DC\FeatureLockDown
- Create a new REG_DWORD (32-bit) value called bProtectedMode
- Ensure the value is 0 (should be by default)
And Adobe now opens!
