Inno Setup installer on Windows XP gives "not a valid win32 application"

At some point after some of the Inno Setup updates, any installer generated with it fails to run under Windows XP, giving the error:

not a valid Win32 application

Is there any setting I can change in the setup script to fix this?

Solution

  • Since version 6, Inno Setup no longer supports Windows XP.

    See Inno Setup 6 revision history:

    • OS requirements change: Windows 2000, XP, and Server 2003 are no longer supported. Windows Vista is now the minimum supported operating system.

    And since version 6.3, Windows 7 and newer is supported only.
