Problem in installing Dot Net Core 1.0.0 VS 2015 Tools Preview 2

Each time I try to install the DotNetCore.1.0.0-VS2015Tools.Preview2.exe package I get an error saying the following:

Setup Failed One or more issues caused the setup to fail. Please fix the issues and then retry setup. For more information see the log file. Setup has detected that Visual Studio 2015 Update 3 may not be completely installed. Please repair Visual Studio 2015 Update 3, then install this product again.

After changing the VS Community UpdateVersion string value from 14.0.25424 to 14.0.25420 in the registry, the installer worked fine for me

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\DevDiv\vs\Servicing\14.0\community
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\DevDiv\vs\Servicing\14.0\community\1033
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\DevDiv\vs\Servicing\14.0\ente‌rprise
