I use the following routine to force a download it appears to work with all files except .msi (microsoft installer)

header('Content-disposition: attachment; filename='.$file_dl);
header('Content-type: application/exe');
readfile('../downloads/'.$file_dl);

changing Content-type to application.msi has no effect

Try application/octet-stream
see if this helps.
