Hi james115,

Welcome to the Forum.

What do you mean by opening an executable? Does Olly display the panes including the disassembly module?

Hi james115,

Welcome to the Forum

You have more chances to get help if your diagnosis is clearer: "I see a messagebox saying..." or "when I do X, nothing happens" etc

Welcome to the forum, James and have fun.

As already said: A detailed description of the error will help to solve your problem.

Hello, thanks to all, when i clik open and i choose the .exe file in the directory  i see the mesage shown in the attacchment
Thanks

It could be a spaces-in-the-path problem. Try the following:
- copy the exe to the folder where Olly sits
- rename it to MyTest.exe
- drag it over OllyDbg.exe

Are you sure it's a 32-bit program? Olly won't load 64-bit code, although I think the message would be different.

[james115]

yes you are right is a 64 bit, since my pc is 64 bit and the software is new

Hi James,

You can try x64dbg :

An open-source x64/x32 debugger for windows.

That is the second message. The first one tells you already the reason:
File 'C:\Masm32\MasmBasic\Res\SkelDualConsole64.exe' is probably not a 32-bit Portable Executable. Try to load it anyway?

Btw for 32-bit code I would use Olly version 2. As Erol (Vortex) already wrote, x64Dbg is a reasonable solution for 64-bit code. The interface has been ruthlessly stolen from Olly, so your learning curve shouldn't be steep at all. In the middle of Opzioni/Impostazioni/Motore you'll find "Skip INT3 stepping". Set it ON. Otherwise it's as simple as inserting an int 3 somewhere, hitting F9 to get there, and continuing with F7 & F8 as in Olly

thanks, i will try to use it
