Enigma Protector

I have an Enigma protected application using an Enigma protected dll.
To improve the dlls security I wanted to use Enigma's VM feature to virtualize key functions.
Sadly the application starts crashing when I virtualize some functions.
The crash only occurs when I utilize virtualization. A normally protected dll and the unprotected dll
are working fine.

edit: Some additional information
Compiler: MSVC6 + MSVC10 (/LTCG + /arch:SSE)
OS: Windows 7 amd64
It's a x86 executable

Kind Regards Tim

Hi Tim,

There is an issue with the VM Marker for Visual Studio 2010, if there is try/catch block inside the marker. This happen with some particular applications.

Try to avoid usage try/catch inside VM, or, for example, around the code inside "try" and inside "catch" with the marker separately.

Hope this will be solved soon.

Hi Enigma,

I don't use C++ exceptions in my code (I even disabled them in the compiler), neither I use SEH __try / __except blocks in the virtualized functions.

Kind Regards Tim

Ok, so you are using virtualization by functions selecting through map file?

If possible, can you please send us all necessary files to reproduce the problem at support@enigmaprotector.com? (including non protected dll, so we will protect it and test). This will help to find a problem quickly.
