Adobe Reader XI – An internal error occurred

Adobe Reader An Internal Error Occurred

I installed Adobe Reader XI on our Windows Server 2012 R2 RDS servers, and we start to get this error when we started Adobe Reader.

After some time on Google i found out that disabling Adobe Reader XI sandbox protection mode fixed the error.

go to the registry and find this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\11.0\FeatureLockDown

Create a new REG_DWORD

Value Name
bProtectedMode

Value Data
0
