Your operating system should, ideally, be up to date on service packs and Windows updates before installing Overseer. The Overseer installer will attempt to install any missing software pre-requisites, primarily the Microsoft .NET Framework 3.5.

Administrator Credentials

To monitor remote machines, Overseer will require you to enter the administrative credentials for those machines. This can be a single domain administrator username/password if all your machines are on a Windows domain, or they may be individually entered if you are using multiple different passwords.

Database Requirements

Overseer normally uses a SQLite database for internal storage. If you've purchased the MSSQL add-in and plan to use MSSQL for your database, you will require Microsoft SQL Server installed, licensed, and functional. You can use SQL Server Express(free) from Microsoft as an alternative to a fully licensed install. MSSQL can be installed locally or on a separate server.
