Where Are WiX Variables Defined?

WiX variables are defined in a file called Product.wxs. This file is located in the same directory as your project file.

The Product.wxs file contains the following XML:

<?xml version=”1.0″ encoding=”UTF-8″?>

<Wix xmlns=”http://schemas.microsoft.com/wix/2006/wi”>

<Product Id=”*” Name=”YourProductName” Language=”1033″ Version=”1.0.0″ Manufacturer=”YourManufacturerName” UpgradeCode=”PUT-GUID-HERE”>

<Package InstallerVersion=”200″ Compressed=”yes” />

<Media Id=”1″ Cabinet=”yourproductname.cab” EmbedCab=”yes” />

<Directory Id=”TARGETDIR” Name=”SourceDir”>

<Directory Id=”ProgramFilesFolder”>

<Directory Id=”INSTALLLOCATION” Name=”YourProductName” />

</Directory>

</Directory>

<Feature Id=”ProductFeature” Title=”YourProductName” Level=”1″>

• <ComponentGroupRef Id=’ProductComponents’/ >
& lt ; / Feature & gt ; & lt ; ! — More Product Elements here — & gt ; & lt ; / Wix & gt ;

< p > As you can see, the Product.wxs file contains XML that defines the product features, components, directories, and media. The WiX variable is defined in the < b > Feature < / b > element with the < b > Level < / b > attribute. The value of this attribute is used to determine which WiX feature to use when building your project.

In this example, the value is “1”. This means that the WiX feature “YourProductName” will be used when building your project.
