Installation File preparation tool NSIs usage summary when developing client software for the customer, to avoid additional cost loss caused by the installation by technicians on-site, we usually make an installation package by ourselves, to ensure that the related resource and environment of the program we developed can be automatically and correctly configured before the client runs. NSIs is a popular tool for creating installation files. It is easy to create and provides a scripting language to define static resource configurations for the environment and program, so that the installation files can be customized, it can automatically generate executable installation packages based on custom script files, greatly simplifying the release of programmers. NSIs provides multiple script demos, which can be directly opened on the UI to view and learn their demos. The script commands are basically used to set the components of the installer: installer title, default installation directory, file to be copied, target address and directory structure, Runtime Environment Settings: Registry, operation during uninstallation: delete the file, registry. Therefore, the corresponding Script Commands include the following types: 1. installer title: name2. default installation directory: installdir3. file to be copied: file4. target address and directory structure: installdir 5. run Environment Settings: Registry, shortcut: writeregstr, createshortcut6. operations during uninstallation: delete files, directories, Registry: delete, rmdir, deleteregkey Note: 1. if the program needs to be installed on the C drive, you need to obtain the admin permission in the later versions of win Vista. 2. To add a directory under the target address, you must set a new output directory after creating the directory. Createdirectory $ instdir \ mplayer
The following is an example of the setoutpath $ instdir \ mplayer script code:; VRA. NSI
;
; This script is based on VRA. NSI, But it remember the directory,
; Has uninstall support and (optionally) installstart menu shortcuts.

; It will install VRA. NSI into a directory that the user selects,
