Hi, I have a problem with step 5. when trying to add operating system installer package. When I try to select path to operating system files I get error: "the specified path does not contain a valid operating system or you don't have permission to access it. Specify a valid path." I have windows 7 64bit sp1 source files extracted locally from ISO and have full permission to the folder. Has anyone seen this before, help is greatly appreciated thanks ht
