Silent install of VLC fails if a previous version is installed
When installing VLC in silent mode it will still popup asking to uninstall the previous version. As silent mode is usually in a script with no user interaction it will fail.
To fix this line 841 in vlc.win32.nsi needs to be changed from
MessageBox MB_YESNO|MB_ICONEXCLAMATION $Message_AlreadyInstalled IDNO done
to the following by adding the silent default option /SD IDNO
MessageBox MB_YESNO|MB_ICONEXCLAMATION $Message_AlreadyInstalled /SD IDNO IDNO done
