Hi,
I have an app I am looking at to understand how the serial is generated to unlock resources within the program.

In this case there is the main program which execuites a secondary exe that manages and deals with the unlocking of addons.

Any tips on how I might debug this second exe in olly? It crashes when I try and run it standalone in olly. I can run the main app in olly and start up the target from within the app, but from there I dont know how I can debug it.

Hopefully I have not been to confusing ..

You can open the main app (without Olly) and launch the target from there. Then fire up Olly and select Attach Process(in the menubar, under the 'open' command) and select the secondary app u wish to debug...

Hope it helped!!

A process can be debugged only by one application.

So there's a good chance that the main application is "debugging" the unlocking code, to prevent you from accessing it.

Make sure that it doesn't do that (by patching that is.. or by disassembling) before you attempt debugging...

Do I understand this correctly? It sounds like you've got the same issue I had in an earlier post on "program with 2 executables" If so there's a 14 year old you need to talk to.


You can observe a lot by watching!
