Visual Studio Installation of Xamarin Updates Failed

This article is based on Visual Studio 2015.

Xamarin updates are available.

Downloaded but installation failed to complete - the installation package could not be opened.

This happened whilst downloading the Xamarin update, the Internet was disconnected.

As a result, the downloaded file was incomplete or corrupted.

The solution is to clear the downloaded files from the cache folder and run the update process again.

Refer to this discussion thread on

Clear all files from the following location except index.xml - or perhaps you might just want to clear all files that you have just downloaded for the day except index.xml.
