I use NSIS for better customization. 7zip is good if there are no interaction with installer but output pack is smaller. QTLite yeap %ProgramFiles% is not working (for the moment ?) QTLite.ini must be in the same folder as QT installer. No command line option. QTLite work great... Cool WMLite11 M6 Clip is working for me. (exept "Le papa pingouin" & "Suzy vend des fleurs" & "Viens que j'te borde") Microsoft "Exchange Unplugged" preview and entire show are working. I think that it must be a conflict between WM10 and WM11. My install is fresh, i never install WM10Lite, only WM11Lite.
