When install DotNet Core on my windows 10 laptop(DotNetCore.1.0.0.RC2-VS2015Tools.Preview1),the runtime package setup failed.

I found some error information from the install log file:

Another Solution is to:

  1. go to the folder where you have downloaded the installer
  2. open the command prompt by Shift+right click -> Open command window here
  3. 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 was able to fix this issue by

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

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.
