I've used the ISO Downloader to download Windows Insider builds before and the last build I was able to successfully download was Insider Preview Client build 16251. Now when I try to use the tool I always get the following message:

"Please log into your Microsoft Account, then choose your download again."

I've logged into my Microsoft Account on every browser I have on my system (Windows 7): IE, Chrome, & Firefox all logged into my MS account at the same time. The MS account I am using is registered with the insider program. Is anyone else getting this same error, if so have you been able to fix this issue?

Hi,

Log into your Live account in the download tool (see attached screenshot). The account needs to have access to the Insider Program.

That did the trick, thank you.
