Inno Script Studio is intended to help you write scripts you can later process with Inno Setup Compiler. In this regard, this tool comes in handy for generating hignly customized Windows installer packages. The utility has an intuitive interface, very similar to that of a text editor, which means that, provided you have the required skills, there are no difficulties to start using it right away.
One of main advantages of this product is that you can decide whether to start from scratch or take advantage of the available wizard instead. Luckily, scripts are presented in a structured manner, which favors their understanding. Likewise, it allows easily picking those files and resources you need to include in the package. Moreover, it is excellent that you will not find any hidden features. For instance, all commands are readily accessible from the menu. But that is not all, you can even create shortcuts to common operations. Finally, the availability of an integrated debugging engine becomes crucial in spotting code errors.
There may be a few limitations as to what this product can do. In this respect, you should not expect it to support cloud deployments or Windows installer platform support.
All in all, Inno Script Engine allows personalizing the creation of installer packages. It perfectly integrates with Inno Setup Compiler, one of the best tools of its type out there. Fortunately, adding more features is possible thanks to its support of plugins. The product is absolutely free, though donations are encouraged.
