![]() ![]() To do so, use one of the following methods: Now, start InstallBuilder and open the Demo project. Of course, this is a very simple case, but it is a good example for demonstrating how rules can work for you. ![]() - If a valid license file is not found on the user's desktop, the product will be installed as a “Trial Edition” and the installer will inform the user of that.If that is the case, the installer will report that it is deploying an “Enterprise Edition”. - Your product will be installed as an “Enterprise Edition” if the installer finds a valid license file, “product.lic”, in the user's desktop folder.Imagine that you want to distribute your product offering with the option of installing it for a time-limited evaluation period, or installing it as a registered “Enterprise Edition”, depending on whether or not the user has a valid license key on his or her machine. We will start with GUI in our first, simple example for a fictitious commercial application for Windows. If you don't already have InstallBuilder installed on your system, you can download the latest version from. This article will explain how to implement conditional rules in your actions, how to select the appropriate rule for each case, and how this can help you to optimize your project and avoid duplicating code. You can set not only one, but a set of multiple conditions that can be evaluated with an AND/OR group logic statement. It allows you to set conditions related to an action or an action group at any step of the installation, and they will be performed only if the condition is met. Rules in InstallBuilder allow you to determine when to perform certain actions depending on the circumstances, variables and user inputs that are involved in the installation. Here's another example of common functionality: You may want to discard or accept user input depending on whether it meets certain criteria. ![]() Or you may want to modify or add some content to a file, but only if it is needed (you don't want to duplicate configuration settings). For example, maybe you need to copy certain files only if the target platform is Mac or Linux, but not if it is Windows. The installation of your application does not have to be a rigid, linear sequence of actions. ![]()
