Application installation did not succeed. Cannot locate application files on the server. Contact the application vendor or your administrator for assistance.

Eu segui o conselho sobreesta postagem e baixadogithub-windows.s3.amazonaws.com/GitHub.application com a versão mais recente do Chrome. Quando tentei executá-lo, recebi este erro:

Application cannot be started. Contact the application vendor.

Com esse detalhe:
