Overview

acproxy.dll executes as a process with the local user's privileges. It is an auto-starting process that used the Windows Task Scheduler service to load when the user logs into Windows (sometimes this is required to bypass the UAC protection). This is typically installed with the program Dolby Home Theater v4 published by Dolby Laboratories Inc. The assembly utilizes the .NET run-time framework (which is required to be installed on the PC). This version is designed to run on Windows 7.
