I am trying to install Unity 5.2.2f1and it gets stuck while installing Visual studio community 2015. The visual studio displays: “Applying: Microsoft SQL Server 2014 Management Objects (x64)” and the Unity Download assistant displays: “Execute: “C:\Users\user\AppData\Local\Temp
sr2D0.tmp\vs_community.exe” /passive /InstallSelectableItems /ChainingPackage Unity3d_Unity”

Try to search for ngen.exe in task manager. After shutting down the process, installation runs smoothly. It might occur several times, so keep an eye if it`s not restarting.
Hope that helps
