Download Inno Setup Compiler 5.5.9

Inno Setup is a free installer for Windows programs. First introduced in 1997, Inno Setup today rivals and even surpasses many commercial installers in feature set and stability.

Inno Setup Compiler is a software solution that allows you to create professional Windows installers, just like the ones delivered with famous applications out there.

Although it all sounds terribly complicated, it’s not, and the way Inno Setup Compiler can create an installer is quite impressive.

The whole installer building has been developed as a wizard, so Inno Setup Compiler will assist you all the time.

You are first prompted to choose the application name and version, as well as the publisher and the application website. Just fill in the information and press Next.

Afterwards, you have to choose the application destination base folder which can be either Program Files or any other custom folder you wish to choose. Again, you must write down the folder name and choose whether to give the user the permission to change the application folder or not.

Next you’re required to provide the path to your app’s main executable file and create a list with all the other files. The next steps come with a few other settings to customize the installer, such as the option to create a desktop or a Quick Launch icon, as well as with the language selection.

And that’s basically it. Sure, it requires some time before you will be ready to build your own installer, but you just have to pay attention to every single step and everything should go pretty smooth.

All in all, Inno Setup Compiler is one of the best setup builders ever created and its freeware license should make it your number one choice too.

On Windows Vista and newer, Setup now supports the Windows Restart Manager API to close and restart applications using files that need to be updated:
• Added new [Setup] section directive: CloseApplications, which defaults to yes. If set to yes and Setup is not running silently, Setup will now pause on the Preparing to Install wizard page if it detects applications using files that need to be updated by the [Files] or [InstallDelete] section, showing the applications and asking the user if Setup s...
