Hi @Anonymous,

This is probably due to your pop-up & redirects blocker preventing you from downloading all of the files, there should be 6 in total for Revit.

Long term you should update your  pop up & redirect settings for your browser, for Chrome this is:

Click on the padlock on the search bar -> Site Settings (on the manage website) -> Pop-ups and redirects -> Allow

Otherwise, here are the direct download links:
