Exeasennuspaketit

Exeasennuspaketit are Windows-specific installation packages distributed as executable files. They package software binaries, libraries, resources and configuration files into a single installer or a set of files that install the software on a target system. The installer typically performs tasks such as extracting files, creating directories, writing registry entries, registering components, creating shortcuts, and optionally installing prerequisites or optional components. They may also include an uninstaller to remove the software later.

Common formats and tools include NSIS, Inno Setup, InstallShield, WiX Toolset and Advanced Installer. These tools generate executable installers or MSI packages, and some wrap an MSI inside an executable. Self-extracting archives created by tools like 7-Zip or WinRAR can also function as installers when executed and followed by an installation step.

Installation workflows usually involve startup checks, a license agreement, a user interface to select components, a destination folder, optional features, and a progress indicator. Post-install configuration tasks and the creation of an uninstall entry are common. Privilege requirements vary, but installers often require administrator rights on Windows to modify system directories, the registry, or installed services.

Distribution and security considerations include code signing, where installers are signed with a digital certificate to verify the publisher and integrity. Signed installers reduce warning prompts and improve user trust, while unsigned or poorly sourced installers may be flagged as risky or malicious.

Limitations include platform specificity to Windows; exeasennuspaketit do not natively install software on macOS or Linux. Some environments prefer MSI packages or portable ZIP distributions for easier management, deployment, or removal in enterprise contexts.
