I have Windows 10 and have been having the same problem. Running as Administrator is helpful. However, I have found that if you are patient and just wait, it takes about 30 minutes for the download to start (it looks like nothing is happening...but something is happening in the background), and then another 30 minutes for the download to complete. I have done this twice, including a download of the NYS Tax program. This is not ideal, and it should not be acceptable to Turbo Tax, but it worked for me and I have E filed two tax returns so far. Hope it works for you.
