About System Requirements
You can define system requirements for an installation in 2 different areas of Wise for
Windows Installer:
! System Requirements page
You can use a point-and-click interface to set requirements for the operating system,
the Internet Explorer version, and screen attributes. You can specify minimum
hardware and software requirements for the installation and set warning messages
that display to the end user if the destination computer does not meet specified
requirements. See Setting a Requirement on the System Requirements Page.
! Launch Conditions icon
This is in Setup Editor > Product tab. It lets you build complex conditions using
Windows Installer runtime properties that test aspects of the destination computer.
See Setting a Requirement by Creating a Launch Condition on page 168
Setting a Requirement on the System Requirements Page
This procedure applies to any system requirement that you set on the System
Requirements page. Notes on specific system requirements follow the procedure.
1. Select Installation Expert > System Requirements page.
2. Double-click a requirement.
The Minimum System Requirements dialog appears.
3. From the drop-down list at the top of the dialog, select a requirement.
Requirements that begin with “All” or “Do not check” indicate that this requirement
is not checked. Any requirement you select includes not only the requirement but
also any greater value. Example: Selecting a Windows version of Windows 98 lets
an installation run on any computer with Windows 98 or any later versions of the
same operating system.
4. In Message Text, enter the error message that appears if the destination computer
doesn’t meet the system requirement. It should communicate to the user why the
installation cannot run.
5. Click OK.
