I think you are out of luck, I don;t think you can download it from anywhere else.
This remote desktop app for Mac is honestly the best remote desktop tool for Mac users who want to connect to a Windows PC. Microsoft Remote desktop 10 allows you to easily gain access to your remote Windows 10, Windows 8 and of course Windows 7 with basically a click of a button.
Maybe also look into http://cord.sourceforge.net
Why don't you try downloading it on your computer and see if you can extract the file from the download? Right-click and show package content.
PS: Is that: https://www.microsoft.com/en-us/download/details.aspx?id=465 the right client?
I can't test it since I don't have a MAC at work.
