If u followed R@dier's tut and after writing the stolen bytes, New Origin here, dumping the process, if u get the above error then i think u have not entered the OEP-->18E78 and then click IAT Search. I got it that way.

@Britedream

PEiD scan shows that there are total four exe's which are ASPR'd
viz.
RegDefrag.exe , RegBackup.exe, RegDfrgSch.exe, SysBackup.exe

As per R@dier's tut and ur instructions i unpacked RegDefrag.exe
but it won't run. I don't get any messages. Nothing happens if i double click it. Is it right britedream? If yes, that means i unpacked it correctly. So i thought that for the app to run I have to unpack the other 3 also. I unpacked RegBackup.exe, RegDfrgSch.exe correctly, i guess, coz same thing if i try to run them. But when i load SysBackup.exe in Olly it fails and give me some DLL not found error. Do u get the same error. Can u explain why?
