Windows Installer (msiexec.exe, previously known every bit Microsoft Installer,[iii] codename Darwin)[4] [v] is a software component and application programming interface (API) of Microsoft Windows used for the installation, maintenance, and removal of software. The installation data, and optionally the files themselves, are packaged in installation packages, loosely relational databases structured as COM Structured Storages and commonly known every bit "MSI files", from their default filename extensions. The packages with the file extensions mst contain Windows Installer "Transformation Scripts", those with the msm extensions incorporate "Merge Modules" and the file extension pcp is used for "Patch Creation Properties".[six] Windows Installer contains meaning changes from its predecessor, Setup API. New features include a GUI framework and automatic generation of the uninstallation sequence. Windows Installer is positioned every bit an alternative to stand up-alone executable installer frameworks such every bit older versions of InstallShield and NSIS.
Before the introduction of Microsoft Store (then named Windows Store), Microsoft encouraged third parties to utilise Windows Installer as the basis for installation frameworks, then that they synchronize correctly with other installers and proceed the internal database of installed products consistent. Important features such equally rollback and versioning depend on a consistent internal database for reliable operation. Furthermore, Windows Installer facilitates the principle of to the lowest degree privilege by performing software installations past proxy for unprivileged users.
Logical structure of packages [edit]
A bundle describes the installation of one or more full products and is universally identified by a GUID. A product is made up of components, grouped into features. Windows Installer does not handle dependencies between products.
Products [edit]
A single, installed, working program (or gear up of programs) is a product. A product is identified past a unique GUID (the ProductCode holding) providing an authoritative identity throughout the world. The GUID, in combination with the version number (ProductVersion property), allows for release management of the product's files and registry keys.
A package includes the package logic and other metadata that relates to how the package executes when running. For example, changing an EXE file in the product may require the ProductCode or ProductVersion to be inverse for the release management. Still, merely changing or calculation a launch status (with the production remaining exactly the same equally the previous version) would still require the PackageCode to change for release direction of the MSI file itself.
Features [edit]
A feature is a hierarchical group of components. A feature may contain any number of components and other sub-features. Smaller packages can consist of a single feature. More than complex installers may display a "custom setup" dialog box, from which the user tin select which features to install or remove.
The packet author defines the product features. A word processor, for instance, might identify the program'southward core file into 1 feature, and the program'southward help files, optional spelling checker and stationery modules into additional features.
Components [edit]
A component is the bones unit of a production. Each component is treated by Windows Installer equally a unit. The installer cannot install just part of a component.[7] Components can comprise program files, folders, COM components, registry keys, and shortcuts. The user does non directly interact with components.
Components are identified globally by GUIDs; thus the same component can be shared among several features of the same package or multiple packages, ideally through the use of Merge Modules.
Key paths [edit]
A key path is a specific file, registry key, or ODBC information source that the bundle author specifies as critical for a given component. Because a file is the most common blazon of key path, the term key file is commonly used. A component can contain at most one central path; if a component has no explicit key path, the component's destination binder is taken to exist the key path. When an MSI-based program is launched, Windows Installer checks the existence of key paths. If there is a mismatch between the electric current arrangement state and the value specified in the MSI package (east.k., a key file is missing), the related feature is re-installed. This process is known as self-healing or cocky-repair. No two components should use the same central path.
Developing installer packages [edit]
Creating an installer parcel for a new application is non fiddling. It is necessary to specify which files must be installed, to where and with what registry keys. Any non-standard operations tin can be done using Custom Actions, which are typically developed in DLLs. There are a number of commercial and freeware products to assist in creating MSI packages, including Visual Studio (natively upward to VS 2010,[viii] with an extension on newer VS versions[9]), InstallShield and WiX. To varying degrees, the user interface and behavior may be configured for use in less mutual situations such as unattended installation. Once prepared, an installer package is "compiled" by reading the instructions and files from the developer's local machine, and creating the .msi file.
The user interface (dialog boxes) presented at the beginning of installation can exist changed or configured by the setup engineer developing a new installer. There is a limited language of buttons, text fields and labels which tin exist arranged in a sequence of dialogue boxes. An installer bundle should be capable of running without whatever UI, for what is called "unattended installation".
ICE validation [edit]
Microsoft provides a set of Internal Consistency Evaluators (Water ice) that can be used to find potential problems with an MSI database.[x] The Ice rules are combined into CUB files, which are stripped-down MSI files containing custom deportment that examination the target MSI database'due south contents for validation warnings and errors. Ice validation can be performed with the Platform SDK tools Orca and msival2, or with validation tools that ship with the various authoring environments.
For case, some of the Water ice rules are:
- ICE09: Validates that any component destined for the Organization folder is marked equally being permanent.
- ICE24: Validates that the production code, product version, and product language have appropriate formats.
- ICE33: Validates that the Registry tabular array is not used for information amend suited for another table (Class, Extension, Verb, and so on).
Addressing Ice validation warnings and errors is an of import pace in the release procedure.
