Cannot build UWP Solution in visual studio 2017

Hi -

I have formatted my computer and installed Unity 5.6 (and also Unity 2017).

I compiled two simple Unity projects for UWP using 5.6 and Unity 2017.

Visual Studio 2015 will not work and tell me to use newer version of Visual Studio.

In Visual Studio 2017, the following errors occurred, which looked like something to do with path...?

Severity Code Description Project File Line Suppression State Error The command ""C:\Users\Joshua Choi\Desktop\New Unity Project 2017\app\Unity\Tools\AssemblyConverter.exe" -platform=uap -lock="C:\Users\Joshua Choi\Desktop\New Unity Project 2017\app\New Unity Project 2017\project.lock.json" -bits=32 -configuration=Release -removeDebuggableAttribute=False -uwpsdk=10.0.15063.0 -path="." -path="C:\Program Files\Unity\Editor\Data\PlaybackEngines\MetroSupport\Players\UAP\dotnet\x86\Release" "C:\Users\Joshua Choi\Desktop\New Unity Project 2017\app\New Unity Project 2017\UnityEngine.dll" "C:\Users\Joshua Choi\Desktop\New Unity Project 2017\app\New Unity Project 2017\UnityEngine.Analytics.dll" "C:\Users\Joshua Choi\Desktop\New Unity Project 2017\app\New Unity Project 2017\UnityEngine.Timeline.dll" "C:\Users\Joshua Choi\Desktop\New Unity Project 2017\app\New Unity Project 2017\nunit.framework.dll" "C:\Users\Joshua Choi\Desktop\New Unity Project 2017\app\New Unity Project 2017\UnityEngine.UI.dll" "C:\Users\Joshua Choi\Desktop\New Unity Project 2017\app\New Unity Project 2017\UnityEngine.HoloLens.dll" "C:\Users\Joshua Choi\Desktop\New Unity Project 2017\app\New Unity Project 2017\UnityEngine.Networking.dll"" exited with code 1. New Unity Project 2017 C:\Users\Joshua Choi\Desktop\New Unity Project 2017\app\New Unity Project 2017\New Unity Project 2017.csproj 266

Please let me know if anyone has a clue! Thanks,
