I finally got chance to install the SCCM 2012 R2 version in my lab today to have a play with the new features.All was going well until I hit the pre-requisites checker on the install media which showed a failed, even though I’d installed the relevant software from the WADK (Windows Assessment and Deployment Kit).SCCM2012R2I assumed it was an error in the checker itself, but upon further investigation it’s not! SolutionFirstly, uninstall the old version of the WADK for Windows 8 from your serverSecondly, install the new WADK designed for Windows 8.1!WADK81Download link – http://www.microsoft.com/en-us/download/details.aspx?id=39306 Hopefully this helps others in a similar situation.Neil
