File download has to be enable.
1. Using Internet Explorer go to > tools > Internet Options > Security Tab.
2. Custom level > Downloas >> File Download select enable
If it doesn’t work than there are two other options that need to be switched to “enable.” If you go further down the list, you should find “Launching applications and unsafe files” as well as “Launching programs and files in an IFRAME” (only necessary for downloads in IFRAME). After changing these two extra settings to enable you should be able to download. I really hope this works out for you guys, cheers!
