Hi, new here - Can ANYONE please help? I had the shortcut in a Movie folder which accidently got deleted. Since then nothing I could do would allow the program to run again. So, I uninstalled the whole programme and reinstalled it (or tried). I have now tried eleven times. Every time a shortcut appears on the desktop, then the installation says 'Rolling back' and an error :1603 during Installation message appears! It's driving me crazy, I need to create a video A.S.A.P. Can anyone help? PLEEZE!
