Q:

Resharper 8.0 in Visual Studio 2013

I've been using Resharper (v8.0.14.856) with VS2012 for some time now, but I've recently installed VS2013. However, Resharper does not appear in the menus for VS2013, or in the options (under Tools->Options).

I've re-run the installer, and selected VS2013. As far as the
installer is concerned, it is installed for VS 2013.
I've tried repairing the install.
I've tried deleting the
%AppData%Roaming\JetBrains folder (as suggested elsewhere).
I've read this:
http://resharper-support.jetbrains.com/entries/21204867-ReSharper-is-not-available-in-Visual-Studio-after-installation and I've tried running Visual Studio with /resetskippkgs command line
key.
I am an administrator, so I've run the installer as administrator, and I run VS2013 as administrator.
I've tried running in Compatibility mode for Windows 7
I've also tried contacting JetBrains, but have yet to receive a reply

Note. I don't have an "\Common7\IDE\Extensions" folder, but I don't have one for my VS2012 install either, and Resharper works just fine there.
Does anyone have any other suggestions?

A:

You need 8.1 to work with VS2013.

This is also marked with a small "8.1" image on this page:
