Same problem when using Chrome on windows 7 Pro laptop. I Cleared Chromes cache no effect , marked the download as unblocked and it worked but it still downloads a file for every new connection. Not good for end users. Switched to Firefox works fine. Problem solved . Hope this helps someone else having the same problem.
How to "Unblock" Right-click on the .exe file, select Properties and then click on the Unblock button – if the file has been blocked, to unlock the file. Credit TheWindowsclub.com
