@waldog – The resolution I posted above is definitely correct for your situation. I would suggest going back and reviewing the setting again. Right now BatchPatch thinks your PsExec.exe is C:\Windows\SYSTEM32\ntdll.dll. You need to modify ‘Tools > Settings > Remote Execution’ to point to the actual PsExec.exe on your system. I would suggest putting PsExec.exe into C:\Windows, and then put C:\Windows\PsExec.exe into the setting noted above. Make sure to save the setting instead of canceling/Xing the window. Also make sure you apply it to the correct user profile. That is, if you run BatchPatch as userA, but you make the setting change after launching BatchPatch in the context of userB, then only userB will have the setting change.
