Help with FMXInno.dll and unarc.dll

[Yourname]

Hi GUYS, I'm looking for a way to use the unarc.dll dll (From Arc/Free Arc), so natively, via vb.net, c++ or Delphi, and looking at BLACKFIRE inno setup templates, which use it, I found a DLL called FMXInno.dll, which, using dumpbin /exports, contains some functions for extracting with Arc (and I think it uses unarc.dll). I would like to know how to use it in my project, and if there is a version/wrapper for VB.net or c++.
