The Developer Preview build does not support asset validation at the current time; faulty content may simply fail to load correctly, or may crash the build.
To install the Developer Release build on Windows 7 or Windows 8, simply unzip the archive and copy the contained TANE folder to your desired installation location.
The default location of the retail build will be the Windows Program Files folder, however you may choose to place the build in any suitable location.
In order to completely clean the build back to a fresh install state, the following steps should be taken: Each release of the developer build is a fresh install and may not maintain backwards compatibility with the user data of previous developer builds.
It is strongly recommended that the user data is cleaned from the machine (see above) before a new build is used.
