Hi guys,

I recently downloaded a Visual Studio 2017 for iOs and after I started an installation process it trows me an exception.

Maybe someone had this error in the past? Will be appreciated for any advise.

Visual Studio installation failed with exception 'Xamarin.Web.Installer.InstallException' (Attempt #3)
Message: Failed to attach DMG image '/Users/qatesting/Library/Caches/XamarinInstaller/Universal/downloads/visualstudioformac-7.6.10.27.dmg'. Error code 1.
