This post is for Microsoft Certified Trainers (MCT) out there that have just noticed that the old download center has been moved to the cloud. I received an error message trying to download some files for a class I am about to teach.
Error message: Unable in downloading file
There is an easy solution. Click F12 in your Internet Explorer browser and lower the document mode and user agent string to e.g. IE 9.
If you use document mode 11, you may see this error:
As always, you will also need to have Microsoft’s File Transfer Manager installed.

When I tried to install the Microsoft File Transfer Manager (FTM) when prompted by the browser, it silently failed or at least did not start installing. So I downloaded and installed it manually from http://transfers.one.microsoft.com/ftm/default.aspx?Target=install and let it run and kept it running while repeating the steps Thomas described and then it went ok.
Hello all
I tried the solution of Thomas and it’s still doesn’t work…
