Hi @Surya0152 ,
The installer sets the VersionNT property to the version number for the operating system, undefined if the operating system is not Windows NT, Windows 2000, Windows XP, Windows Vista, Windows Server 2008, or Windows 7. The value is an integer: MajorVersion * 100 + MinorVersion.
Which type of Installshield project it is?
Based on that you can use Installation Requirements section which you would find under Project Assistant.If you can't view Project assistant tab,do enable it from View Ribbon->Project Assistant
For Installscript project,you can use platform filtering option from General Information view
