Another Solution is to:

go to the folder where you have downloaded the installer
open the command prompt by Shift+right click -> Open command window here
Type - dotnetcore.1.0.0-vs2015tools.preview2 SKIP_VSU_CHECK=1 and hit enter

This should skip the VS update check and start the installation normally.

I still have the same issue :( – etrupja Jul 29 '16 at 19:11
@eg16 If you aren't doing so already, make sure you are running the command from a cmd or PowerShell window in Administrator mode. – pwdst Aug 02 '16 at 11:48
What a charming little solution. Thanks! – blueprintchris Nov 30 '16 at 11:44

I was able to fix this issue by

turning off Antivirus
clearing the %temp% folder
running the DotNet Core (DotNetCore.1.0.0.RC2-VS2015Tools.Preview1) again in repair mode

Just clearing the `%temp%` folder helped me solve the same problem with installing the `.net core 5 runtime` – LeffBA Jan 11 '21 at 08:00

After applying the other answers here the install was still failing for me. Periodically during the install, a pop-up warning dialog would open stating "The account already exists". I reviewed the Programs and Features list and saw 3 different entries for the VS2015Tools preview. I right-click Uninstall'ed each of them (which removed each one almost immediately), and tried the install again. This time it completed without errors.
