What Is CreateInstall and When Should You Use It?

CreateInstall is a Windows installer builder for people who want complete control over the installation process. Instead of relying on preset wizard behavior, you build an installation as a sequence of commands that you can inspect, reorder, and extend. It fits best when your setup needs custom operations or when other installers keep hitting a feature wall. The site lists it as freeware and trial software, with purchase options available.

How CreateInstall Works

The core idea is that the entire installation process is presented as a sequence of commands. You can use the commands already provided and add any operations you require. Your installation packages do only what you tell them to do, which is what gives you control over both the install and uninstall processes.

For anything beyond the built-in commands, the installation script language is Gentee, described as a universal programming language. That is the mechanism behind the "unlimited scalability" claim: custom logic isn't a workaround, it's the intended extension path.

You can also modify the interface of your dialog boxes and add your own resources and graphic items. The site states that about 100 KB of source code used in installation packages is at your disposal.

When It Fits

Choose CreateInstall when:

• You need to know what your installation package does step by step and want it to perform certain operations at certain times.
• Your requirements change over time and you need an installer that can absorb those changes.
• A feature is missing from another installer — the site's position is that it is highly probable the feature is already implemented in CreateInstall or can be implemented in it.
• You want to control the install and uninstall processes rather than accept defaults.

If you just need a standard setup with no custom steps, the command-sequence model is more machinery than the task requires.

CreateInstall Assistant

When you install CreateInstall, you also receive an additional application called CreateInstall Assistant. It has a very simple interface and lets you quickly create installations without additional study of the program. Treat it as the entry point for straightforward packages, and the main program as the path for full command-level control.

Compression Options

Compression is one of the installer's components, and CreateInstall gives you a choice between two basic algorithms:

You can use both algorithms for different groups of files in one installation package, and the compression component has additional settings for tuning. This matters when part of your payload should be as small as possible and another part should unpack as fast as possible.

System Requirements

• Operating system: Windows XP/Vista/7/8/10
• Installations created with CreateInstall work on Windows XP/Vista/7/8/10

Practical Notes

• The site's navigation includes Download, Purchase, Documentation, Support, and Contact us, plus a log-in option — so documentation and support are the places to go for the Gentee scripting details.
• Pricing is not stated on the page beyond the presence of "Buy now" links, so check the store links for current terms rather than assuming a free tier covers your use.
• Because the whole process is a command sequence, plan to read the documentation before building anything non-trivial; the Assistant exists precisely to avoid that step for simple cases.
