Document Protection, System Integration

[Thankful]

How is 'System integration' different from 'Enable document protection' ?

[Marcos]

Enabling system integration will register dmon.dll in the system (ie. write the necessary changes to the registry) while the latter only enables/disables protection. It's similar to real-time protection - if the driver is loaded protection can be enabled or disabled.

System integration must be checked. Otherwise, nothing is enabled.
