nirsoft_installer looks in the directory where nirsoft_installer.exe is for any files it needs before attempting to download them. If it does download a file, it will attempt to save a copy of the file in this same directory.

nirsoft_installer adds the installation directory to your PATH environment variable. On 32-bit systems, this directory is usually C:\Program Files\NirSoft. On 64-bit systems, this directory is usually C:\Program Files(x86)\NirSoft.

If the program is a Windows GUI application, an icon is created in the C:\Documents and Settings\%username%\Start Menu\Programs\NirSoft directory.

Applications that require Windows 98, ME, or NT 4.0, are listed as such.

Note: you are responsible to verify that each program you install using nirsoft_installer is designed to work in your environment. If you are unsure, then please visit for more information.
