If Statement
Use If Statements to set conditions on actions. An If Statement marks the beginning of
a If block, which is a conditional block of actions. The If block must be concluded by an
End Statement. If the condition specified in the If Statement is true, the actions inside
the If block are executed; if false, the actions are not executed. You can nest If
Statements to create complex conditions.
The condition you enter in the Condition field is subject to Windows Installer guidelines
for creating conditions.
See Conditional Statement Syntax in the Windows Installer SDK Help.
To use the Condition Builder to create a syntactically correct Windows Installer
condition, click Build.

Creating Conditions With Condition Builder
