Sorry to ask something as simple as this. Trying to convert the ESDs from the isos created with the MCT and all Im getting is "There is a problem reading the index architecture". As far as I can tell the RSA key is correct in the .cmd (BwIAAA...) Am I doing something wrong? Also, where is the thread for the tool, Google takes me all over the place and cant seem to narrow it down. ;edit; Right first hurdle over, seemed I was using an old version. Now found 6.7 but the new error is "ERROR: Specified file is not original microsoft ESD file. the original file would contain 4 images."
