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
