Get Windows version: Difference between revisions

Revision as of 21:11, 22 June 2015

Semi-Obsolete

NSIS includes a header file aptly named WinVer.nsh since version 2.21. It allows for easy detection of the Windows version using LogicLib macros and has automatic future-support so you can always tell if the system at hand, even if undetected, is newer or older than what you need.

!include WinVer.nsh
 
Function .onInit
  ${IfNot} ${AtLeastWinXP}
    MessageBox MB_OK "XP and above required"
    Quit
  ${EndIf}
  ${If} ${IsWin2003}
  ${AndIfNot} ${AtLeastServicePack} 1
    MessageBox MB_OK "2003 SP1 is required"
    Quit
  ${EndIf}
FunctionEnd

The current stable release of NSIS (2.46) only supports up through Windows 7 and Windows 2008. The alpha release of NSIS (3.0a2) supports Windows 8 and 8.1. If you wish to detect Windows 8 and 8.1 rather than just ${AtLeastWindows7} or similar with NSIS stable you can use this script or update your local WinVer.nsh with the missing defines and macros from NSIS 3 (This will fix Windows 8 but 8.1 lies unless you have the correct manifest).

Description

A simple function to return the version of Windows that the script is running on. It can detect Windows 95 through Windows 8.1, returns the version number if it is Windows NT 3 or 4 and returns a blank string if it can not determine the Windows version.

Usage

Include the script as normal in your NSIS script. Call it as:

${GetWindowsVersion} $R0

At this point, $R0 will contain one of the following: 95, 98, ME, NT x.x, 2000, XP, 2003, Vista, 7, 8 or a blank string (for unknown). For NT 3 and 4, the version number will be included.

Alternate Script With Server Versions

This alternate script distinguishes between Desktop and Server versions of Microsoft Windows. It breaks compatibility with existing usage due to having these new versions included (e.g. for Server 2008 R2, this script will return '2008R2', whereas the script above returns '7').
