About System Requirements
If the destination computer is running Windows 95, Windows 98, or Windows Me, the
minimum system requirements specified under the Windows Version item are checked
instead.
Screen Resolution
The minimum required screen resolution.
Screen Colors
The minimum required screen depth. 24 Million Colors corresponds to True Color in
the Display Control Panel.
Internet Explorer Version
The minimum required version of Microsoft Internet Explorer.
Windows Installer Runtime Version
Rather than have the installation fail if the destination computer lacks the required
version of Windows Installer, you can set the installation to pre-install a later version of
Windows Installer. Use the Prerequisites page to pre-install Windows Installer; see
Adding Prerequisites to a Release on page 189.
SQL Server Version
This option is useful if you have set up this installation to configure a Microsoft SQL
Server on the SQL Server Scripts page. By default this value is not checked. See
Configuring a Microsoft SQL Server During Installation on page 226.
IIS Version
This option is useful if you have set up this installation to configure a Microsoft Internet
Information Services (IIS) server. By default this value is not checked. Also see About
Web Installations on page 217.
If you set an IIS Version, then an additional list of requirements appears, which are
settings available in IIS 6.0 and later. These requirements match those that are in
Internet Services Manager under the Web Service Extensions folder icon. You can
double-click any of these requirements to check its state as set on the destination IIS
Web server.
.NET Framework Version
This verifies the version of the Microsoft .NET Framework.
Also see:

Setting a Requirement by Creating a Launch Condition
You can use launch conditions to check system requirements on the destination
computer. (Example: The value of properties or environment variables.) Windows
Installer defines several properties at runtime that are useful for defining conditions.
See Hardware Properties and Operating System Properties in the Windows Installer SDK
