you can try this:

First you need define correct mime type/content type of download file

In your case is: application/vnd.ms-powerpoint

So code will be:

 $mime = 'application/vnd.ms-powerpoint'; // Generate the server headers if( strstr( $_SERVER['HTTP_USER_AGENT'], "MSIE" ) ) //id browser is IE { header( 'Content-Type: "'. $mime .'"' ); header( 'Content-Disposition: attachment; filename="'.$filename.'"' ); header( 'Expires: 0' ); header( 'Cache-Control: must-revalidate, post-check=0, pre-check=0' ); header( "Content-Transfer-Encoding: binary" ); header( 'Pragma: public' ); header( "Content-Length: ".filesize( $data ) ); } else { header( "Pragma: public" ); header( "Expires: 0" ); header( "Cache-Control: must-revalidate, post-check=0, pre-check=0" ); header( "Cache-Control: private", false ); header( "Content-Type: ".$mime, true, 200 ); header( 'Content-Length: '.filesize( $data ) ); header( 'Content-Disposition: attachment; filename='.$filename); header( "Content-Transfer-Encoding: binary" ); } readfile( $data ); exit;

where is the download file going? my ajax request sends succes but i can't see any download.
oh. you are using ajax... so i have idea: you can use ajax to open new browser window (or tab) with filled download url or use document.location(download_url);
i am sending the id of selected row name, and in php i am getting this name with $_post. I work with classes and functions
Do you have download url from your code ? if have then you try past it on web address -> enter and see what will happen (dialog save file show up or not)
