# System Manager Prerequisites Installation

The Prerequisites installer performs a system check installs the following software as needed:

- Microsoft .NET Framework 4.0 Full for Windows 7 and below OS

- Microsoft Visual C++ 2010 Redistributable package (x64)

- Microsoft Visual C++ 2010 Redistributable package (x86)

- MSXML 4.0 SP3 for all OS

- Microsoft SQL Server 2012 (x86 & x64)

If the EMSERVER instance is created in an already-installed version of SQL Server (licensed SQL or SQL Express), the installer will skip SQL installation.

| If you prefer to use a licensed SQL server on a remote machine, the Prerequisites installer will still install a local EMSERVER SQL Express instance. After installation, you can select the remote SQL server in the System Manager Configuration tool (see Run Quickstart), and then delete the local instance.

Install Prerequisites:

1. Right-click the System Manager Prerequisites installer file and select Run as administrator.

2. In the System Manager Prerequisites wizard, click Install to begin the installation.

Once complete, the wizard ends automatically.
