Does this Mobile development with .NET impact in anyway Windows UWP development? I don't really need the Android development tools at this moment.

What is the best course of action for this - I tried the install twice, with the same result - can I install the components later on their own?

EDIT: Visual Studio seems to run correctly, and I can open my UWP project and run it so everything seems to work ok so far. This is the version of the application that was installed

Microsoft Visual Studio Community 2017
Version 15.0.26228.9 D15RTWSVC
Microsoft .NET Framework
Version 4.6.01586
Installed Version: Community

See if you have this file on your machine:

%programfiles(x86)%\Microsoft Visual Studio\Installer\resources\app\layout\InstallCleanup.exe

If so, please launch it from an admin command prompt with a -full param:

InstallCleanup.exe -full

If not, please manually delete the folder:

%programfiles(x86)%\Microsoft Visual Studio\Installer

Relaunch the newly downloaded vs_enterprise.exe (or vs_professional.exe or vs_community.exe). Allow the first step to install the installer.

Once the installer comes up and you can see workload choices (.NET desktop and the like), close it. Go launch the same InstallCleanup.exe to clean up old build of VS.

Then relaunch vs_enterprise.exe and install
