[b]Program's Version:


Version 13.00.0014 (Not Beta)


Programs's Download Link:
Request from
Code:
http://www.meliar.com/


Evaluation not freely available. Need to request through this site and they send a link to your email address of a fully functional 30 day evaluation copy. Catch is they ask for Name, company name and phone number and contact you to ask for the reason/s you would want it.
To save you time I have already done this. I've uploaded the program set-up file to link below
Code:
http://rapidshare.com/files/167823827/Setup_MPanel_130DWD.rar.html



Other Attempts:

Spent weeks trying to learn from tutorials how to reverse visual basic.
Tried many tools but could not jump online activation.


Setup File Size:

4.5MB


OS: XP/NT/Vista/Win98

Limitation: 30 Days Trial, fully functional

Registration Type and install process:
1. Install
2. Insert request code provided by company: US-99639529
3. Program authenticates request code online and 30 day evaluation begins
4. Program then looks for
Code:
AutoCAD
and if it's not running offers to start it as it runs on top of
Code:
AutoCAD.



Description:


Application use: Draw 3D spaceframe with
Code:
AutoCAD.
This program then adds fabric sails mesh to frame, relaxes the mesh and produces flat panels for cutting out and welding together.

Random Example of use:

This site selected by Google search and has nothing to do with me. Just selected to explain what can be achieved with the program
Code:
http://www.basestructures.com/


Footnote:

I really don't like to put people out. If there is someone who is willing to help me crack this myself I'd be really obliged.

Thanks

Pauline

The application was compiled to P-Code. Use P32Dasm or VB Decompiler Pro to analyze Smile


P.S. What is Virtual Basic ? Laughing

I meant visual basic (Late night).
Thanks for your input. Did you check it out?
If so does it look difficult to crack? Is it Newbie material?
Pauline Very Happy

The program uses component registration scheme called 1way (atma-software.com/1way), ver. 5.9. It's contained in MPReg2.dll (written in Delphi). Looks easy.

Edit:

Even found a tutorial for older version of it: woodmann.com/krobar/nag/ns64.txt. Should give you an idea.

Thanks for going to all the trouble for me. I really appreciate it.
I got the tute, the tools and the latest version of 1way.

Excuse my ignorance from here on in:

1. I understand that Flux, as an example, is hacking 1Way.dll in the 1Way program files to produce a new .dll and so crack the 1Way program? The 1way program I assume is protected by the authors own method = 1way.dll.

2. The author of the program I'm trying to crack has produced a .dll via 1Way and renamed it MPReg2.dll?

3. So I need to work on MPReg2.dll in the manner described in the tute?

4. What Flux seems to be saying is that if I was to take the cracked MPReg2.dll and rename it to the protection .dll of any other program protected by 1Way it would work?

Am I on the right track?

How did you discover the method of protection? What tool/s did you need for this? Is there a universal tool? I'm coming to understand that there's stacks of different tools out there to choose from. Knowing which one to use is the problem.

Yes, you're on right track. Basically, to crack this scheme, you need to modify MPReg2.dll functions, so that their return values were same as expected by the program to work as registered. However, in this particular case, 1way seems to be implemented to handle internet authorization only. Except for that the program is fully functional, right?

A good debugger is the only tool you need in most cases. OllyDbg is what I use. Of course good knowledge of assembly language is a must. To disassemble VB P-code compiled apps, you need a program that handles the pseudo code, which is VB Decompiler Pro for example.

P.S.

Changing
Code:
0040488D   BADC0A4500   MOV EDX,450ADC

to
Code:
0040488D   BA8C8C4200   MOV EDX,428C8C

seems to be funny way to bypass internet authorization Laughing

Cheers
