Probléme win32 pour lancer une aplication

Bonjour, en ce moment je créer un installateur avec Inno Setup , à la fin de l'installation je veut que deux programmes se lancent tous seul (hamachiinstal.msi et Installation aprés.txt) mais quand j'essaie voila le message d erreur que cela m'affiche :vCreateProcess a échoué ; code 193%1 n'est pas une application Win32 valide.

Voici les codes que j'ai utilisé :

#define MyAppName "****-****" 
#define MyAppVersion "v1.2" 
#define MyAppPublisher "***** & *****" 
#define MyAppURL "[******************.fr]" 
#define MyAppExeName "UpLauncher.exe" 
#define Hamachinstal "Instal Hamachi\hamachiinstal.msi" 
#define Hamachiprep "Instal Hamachi\Instalation aprés.txt"
