Environment for creating farm solutions with SharePoint 2013

(Update from 2022: This article is about Preview version of SharePoint 2013. It may not be relevant anymore.)

Installing my development environment, I have:

1.  Virtual Machine with Windows Server 2012

2.  SharePoint Server 2013

3.  Visual Studio 2012

I need one more element - Visual Studio Tools

Using Platform Installer, I run into problems with Workflow Client 1.0 Beta

It seems, that Workflow Client 1.0 is already installed, and it is not Beta version.

UPDATE:

On 12 November, new version of Office Tools have been announced.  When you download this file, you will notice, that the name changes from "RTMPreview" to "GA".

I strongly recommend installing this version instead. Remember to close Visual Studio during installation.
