Important features such as rollback and versioning depend on a consistent internal database for reliable operation. Microsoft encourages third parties to use Windows Installer as the basis for installation frameworks, so that they synchronize correctly with other installers and keep the internal database of installed products consistent. Windows Installer is positioned as an alternative to stand-alone executable installer frameworks such as older versions of InstallShield and NSIS. New features include a GUI framework and automatic generation of the uninstallation sequence. Windows Installer contains significant changes from its predecessor, Setup API. The installation information, and often the files themselves, are packaged in installation packages, loosely relational databases structured as COM Structured Storages and commonly known as "MSI files", from their default file extension.

ORCA lets you dig directly into the MSI and see the raw data and edit the MSI or create MSTs. While the MSI format itself is an open and "standard" format, a tuner tool is always preferable because you may not know or find documentation on what the MSI rules mean for the particular package. ORCA (part of the Windows SDK) and "Installation Tuners" (like what is available at for Acrobat or the Office 2003 Resource Kit) allows you to create your own MST files for these programs.
