Hello, Just upgraded from SCCM 2012 to SCCM 2012 R2 including WADK 8.1. Every time I want to add a Operating System Installers (win 7 / win 8 / win 8.1) I get the following error message: "The specified path does not contain a valid operating system or you do not have permission to access it. Specify a valid path" I am searching now for 2 days for a solution but can't find is. This is very frustrating... So far I have done the following: Installed WADK multiple times Checked security multiple times create new share and security checked wim file (it is ok, can be mounted by the windows tool) When I install an Operating System Images it also produces the same error message, but when I wait a few minutes than it works.... Does anyone know what the problem is here...? With kind regards, StefanT
