base64 - Internet Explorer fails opening a pdf string file [SOLVED] -

i receive (from webservice don't manage) string content of pdf file.

on client's side, use function:

window.open('data:application/pdf;base64,'+encodeuri(thestringwiththepdfcontent));

as usual, works in every browser ie (11 in case), shows alert message: "do want allow website open app on computer?"

if no, empty white page opened.

if yes, tries open "data" file (as reads protocol in window.open, guess) and, doesn't find application that, sends me microsoft application store, suggests me download "imusic"

completely useless, of course.

i've changed internet options i've guessed help, none works.

any suggestion?

thanks in advance,
