问题
I am using Visual Studio 2015 . I have installed vs2015 from iso . VS2015 is installed . But Now i am going to installed xamarin tools for visual studio 2015 but when i started the package faced this error
I am downloading Xamarin Tools from here - https://www.xamarin.com/download
I have seen the stack overflow question here - "A Setup Package is either missing or damaged" error while installing Visual Studio 2015 on Windows 10
It is said in question link that error is resolved 8 months ago it was error in setup . But it still exist
I am trying to install xamarin tools in vs 2015 got setup but it came with error above no xamarin / mobile apps tools installed if skip the error
What could be possible solution please?
