Latest Dorico update refuses to install (Windows 10)

It refuses to install (Windows 10). I have tried twice, using the Steinberg Download Assistant. It downloads and starts to install but then stops and says “An installation package can’t be found. Try installation again using a valid copy of Dorico35.msi”. ???

I checked, and no such file has been downloaded to my computer.
