7. Extract the reset_fp10.cmd. Important: Be sure that both the subinacl.exe and reset_fp10.cmd files are in the same location (folder)
You really need to be sure that you're running the reset_fp10.cmd in the same folder. It installs by default to the "C:\Program Files\Windows Resource Kits\Tools\" folder. So, be sure that the reset_fp10.cmd file is in this folder as well.
Maybe try that step again?? It worked for me as soon as it finished running.
