Can t install APK from browser downloads

Question

I ve downloaded an APK from web  using the default browser and it can t be opened from the Browser -  Downloads   It tells me  Can t open file   But I can use a file browser  like OI File Browser  to browse and open this APK  and it works well   What could be the problem here  Is it about the HTTP header

It shouldn t be HTTP headers if the file has been downloaded successfully and it s the same file that you can open from OI   A shot in the dark  but could it be that you are not allowing installation from unknown sources  and that OI is somehow bypassing that   Settings   Applications   Unknown sources     Edit  Answer extracted from comments which worked  Ensure the Content-Type is set to application vnd android package-archive
