Something like this should do it: <!-- If Var1 not defined use preset value --> <?ifndef Var1?> <?define Var1 = "Value1"?> <?endif ?>

Subject: [WiX-users] How to assign a default value to preprocessor properties I am using preprocessor properties in my WIX project and I assign them values in msbuild when building the WIX project from the command line . For example I have the following preprocessor properties: Var1=$(Var1);Var2=$(Var2) I assign them values in msbuild in this way: msbuild /p:Var1="value1";Var2="value2" The problem is that when I build the project in Visual Studio those properties get an empty value. I want to give these properties a default value so that I will be able to build the WIX project from Visual Studio and not just from the command line using msbuild. Is there any way to assign these properties a default value that can be overridden by msbuild ?
