Answer 1

Answered by Damian Edwards in his comment on the announcement page:

Please note, if you're experiencing an error when trying to install RC1 on Windows "0x80091007 - The hash value is incorrect", delete any previous MSIs for DNVM and ASP.NET VS tooling from the folder you downloaded the RC1 installer to. We're working to fix this issue.

Answer 2

I was able to fix it by moving to a different folder (desktop in this case)

Answer 3

After I moved the loader to a new folder, still no joy. Tried several times with different locations. No luck, same error.

I finally went to the C:\ProgramData\Package Cache folder and found the most recent package (only had one today from my first install attempt). I deleted that.

After that, I was able to use the AspNet5.ENU.RC1_Update1.exe to successfully install the update.

This seems a lot safer to me than removing all of the Package Cache folder contents. Which I've read will surely impact other aspects of your VS install.
