Editing CAB File - Help
 

I tried to import a .DLL file to a Cabinet File (.cab) from a software's application folder. I tried installing the application but half way it prompted with " .cab is not digitally signed ".

Without saving the .DLL file I can install the application just fine, but every time I save it inside the .Cab file I get that error.

Is there a way around this, ?
Can I extract the CAB file and then replace the .dll and make a new cab file ?

You cannot digitally (re)sign an installation package if you don't have the original key for that. (So you will have to remove the check for the digital signature in the installer.) That aside, for Micro$oft CAB archives, use MsCab, for InstallShield CAB archives, i5comp and i6comp.

Thanks, but how do I remove the check for the digital signature in the installer ?

That's exactly what we call hacking - which is the general form of cracking -: modifying a software in a non-orthodox way, for a non-orthodox purpose. There's no step-by-step guide for that.

cool thanks for the info.
Now the only problem I seem to have is creating the .cab file :(
I tried : makecab.exe but it doesn't do anything. I get the DOS window , but it goes off immediately.
I put the makecab.exe in the folder that I have my files ready to make the cab, but nothing happens when I open it.

thats because it requires switches to run, which its best to do in a permanent dos window.

Goto start > run > and type in cmd

Yes now I am on MS-DOS Command prompt and I specify the path of the .cab or the files to make the cab but using the commands nothing happens.
