ranamaj - I had similar issues some days ago with Dism errors and other problems running the AIO_New_2.3.cmd.script. Admin logon and priviledges, tried cleaning up, etc still no better. I had turned off defender and real time and all that stuff, but still failing until I white listed the simplix folder - it seems some silly MS protection was still running despite all showing as disabled. Worth making sure all AV and real time stuff is off and add exclusions for the place you added the scripts and files. btw - the cleanup did not always clean things until whitelisting the folder.
