Description

Windows OS contain special API for OS version detecting. But standard NSIS 2 pack not use this.

My special plugin "Version.dll" use OS API (function GetVersionEx() from "kernel32.dll") for OS version detecting.

Plugin contain function:

• GetWindowsVersion (get major, minor version, build number, platform id, service pack name);
• simply OS detect function (IsWindows31, IsWindows95, IsWindows98, IsWindowsME, IsWindowsNT351, IsWindowsNT40, IsWindows2000, IsWindowsXP, IsWindows2003);
• simply OS platform detect function (IsWindowsPlatformNT, IsWindowsPlatform9x);
• simply "good" OS detect function (IsWindows98orLater);

Size of plugin "version.dll" is 6144 bytes
