Can't uninstall .NET 5 RC1

I had the same issue, I found it by googling the KB id. http://download.microsoft.com/download/B/0/A/B0AEBD7D-6979-4265-B1AC-A0B73618FB22/AspNet5.ENU.RC1_Update1.exe

or this:

http://download.microsoft.com/download/1/8/0/18048EDD-9F45-479A-B208-6F7C91CF2ECC/AspNet5.ENU.RC1_Update1_KB3137909.exe

I downloaded only AspNet5.ENU.RC1.exe file from here: https://www.microsoft.com/en-us/download/details.aspx?id=49959 start it and run "uninstall". The uninstallation procedure with this file, for ASP.NET 5 RC1, works without problems.

I managed to uninstall it by downloading the installer from asp.net and tried to install it by double clicking on the file. It gave an option to repair and uninstall.
