How to tell the virtualized application the directory of the thinapped executable location?

Hi, wrote a software that I want to distribute to my customers. I still evaluating ThinApp and my intent is to use ThinApp as a simple protection against .net decompilation, and other things.

Well, that said, I will give and example of what I trying to do:

I installed my application on directory "C:\Program Files\MyApp" and then I virtualized it. The result is the MyVirtualApplication.exe

Now I will distribute the MyVirtualApplication.exe to my customers as a single exe that my customers can run from any directory he wants. What I want to do is let the customer create a config.ini file that will be in the same directory as the MyVirtualApplication.exe.

How can I pass to my application the directory where the MyVirtualApplication.exe is running from, so I can proper read the configuration files on it?

I will appreciate any help.

Thank you.

Teus.
