Your app should return 0 for success, and anything else for failure. Then your NSIS script could do this:

onInit

  ClearErrors

  ExecWait'C:\ProgramFiles\YourCompany\YourNetApp.exe' $0

 ${If} ${Errors}    

   Abort        ;cancel uninstall 

 ${ElseIf} $0 <> 0

    Abort ;cancel uninstall

>${EndIf}

>FunctionEnd
