Windows Installer SDK
Software development is a rather specialized area, which requires both advanced knowledge and the appropriate utilities in order to be able to successfully create and deploy applications. When it comes to the setup packages specific to Microsoft Windows, the toolkit that is required is Windows Installer SDK.
Inside the bundle are included all the needed tools, components and documentation to help developers get started as soon as possible and create the MSI packages for their software. Besides the necessary Windows Installer Development Tools, a set of samples are also part of the collection, not to mention the libraries and headers.
Windows Installer SDK facilitates not only the creation of application setups, but it is also equipped for editing existing MSIs. This means that it can make the correction of bugs or addition of new features even more facile for programmers.
One of the most coveted tools that is especially designed for modifying Windows Installer packages, Orca, is included in the development kit and constantly updated, so as to offer the best performance and functionality to its users. It is ready to be used for merging modules and comes with a dedicated GUI for validation.
The setups build or modified with Windows Installer SDK should be validated prior to the first install, just to make sure everything is in good order with the components that are included and will be deployed onto the target system. An important part of the toolkit is the Help file that is included to offer vital information that helps a lot in understanding how some of the package constituents work.
All things considered, when it comes to authoring MSI installers, it's quite certain that Windows Installer SDK is a must have software for any developer because it comes with everything necessary to streamline the process of building this particular type of setups.
