iViewRipper is a great app !

Worked perfectly first time. I'm a Mac OS X user and so can't run Windows apps (currently running iViewRipper in Win8.1 Enterprise trial in a VM).
I use WINE to run a lot of Windows apps under OS X. But, when I tried iViewRipper it terminated badly saying:
System.TypeInitializationException: An exception was thrown by the type initializer for ﺌ벨특�걗 ---> System.ArgumentOutOfRangeException: Token 0x40000e6 is not valid in the scope of module iViewRipper.exe
This is probably because I'm missing critical dlls in my WINE prefix. Can you advise on what dependencies iViewRipper has ? For example, does it require a particular version of .NET ?
Many thanks.
