Using Custom Variables


Since version 1.2.3 InstallForge allows you to define custom variables that can be used for other parameters your setup needs. InstallForge will use the Windows registry in order to set the values of your variables.


As of InstallForge 1.4.0, you need to enclose the name of your custom variables with brackets [ ] when using them.

Create a New Variable

To create a new custom variable, complete the following steps:

  1. In the InstallForge Builder Environment, click Variables in the explorer bar.

Specify Variable Details

In the next step you have to define the name of your variable, parameters for the Windows registry and a default value on the Add Variable window. If the setup is not able to find the value name you specified for the registry, it will use the default value. Finally click on Ok in order to create your variable.


It is always a good practice to define a default value.
