Yeah, this is why I use the following AutoIT script to close that error message and install Nero 7.2.0.3: AutoItSetOption("TrayIconHide", 1) BlockInput(1) Run(@ComSpec & " /c " & 'Nero.msi /qb-! STARTPARAM=CallFromExe', "", @SW_HIDE) Sleep(4000) Send("{ENTER}") WinWaitClose("Nero 7") Sleep(2000) BlockInput(0) I customized my Nero.msi with Installshield, so only my the components that I want get installed, slimmed down the installer to a 38,2 MB sfx archive now.
