I had a similar experience downloading the PU last week using Chrome. I reverted to IE and pulled it down. I tried it again later in the day after having closed Chrome and it worked like a charm. I can't say what resolved the issue.
I had a similar experience with downloading a copy of Microsoft Power Query last week as well. Changing to IE allowed me to pull down the file. The issue resolved itself later in the day having closed Chrome once or twice.
Happy Computing!
