    A Microsoft and Xamarin engineer are investigating the issue. It appears to be a bug in the software which is system depended.

    We are using Visual Studio 2015 and a new developer joined our team and after downloading the Xamarin Installer for Windows from https://store.xamarin.com/account/my/subscription/downloads and running the Installer, he gets an error that he must install everything manually.

    Looking at the Logs, we see the same issue:

    [2017-03-15 18:25:41.935] [Exception] Failed to retrieve response for URL 'https://www.xamarin.com/installer_assets/v3/Windows/Universal/InstallationSizes.xml' [2017-03-15 18:25:41.935] [Exception] System.Net.WebException: The remote server returned an error: (403) Forbidden.

    If I point my browser to https://www.xamarin.com/installer_assets/v3/Windows/Universal/InstallationSizes.xml , I get -

    <Error>
    <Code>AccessDenied</Code>
    <Message>Access Denied</Message>

    </HostId>
    </Error>
    

    Xamarin folks: can you please fix this?

    Having to install Visual Studio 2017 to solve this issue is not a solution.

    The installer error page is as follows:

    A Microsoft and Xamarin engineer are investigating the issue. It appears to be a bug in the software which is system depended.

    Short of re-installing VS 2015, I installed VS 2017 and that resolved the problem.
