Overview

During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. Upon being installed, the software adds a Windows Service which is designed to run continuously in the background. Manually stopping the service has been seen to cause the program to stop functing properly. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The primary executable is named a2start.exe. The setup package generally installs about 42 files and is usually about 162.69 MB (170,589,246 bytes). The installed file a2update.dll is the auto-update component of the program which is designed to check for software updates and notify and apply them when new versions are discovered.
