The title actually says it already: I want to run MeGUI under Linux. So I downloaded the archive from SF.net, extracted it, opened the folder in Terminal and ran "mono ./MeGUI.exe". Here's the log:

Code:
[ERROR] FATAL UNHANDLED EXCEPTION: System.EntryPointNotFoundException: IsWow64Process
  at (wrapper managed-to-native) MeGUI.OSInfo:IsWow64Process (intptr,bool&)
  at MeGUI.OSInfo.isWow64 () [0x00000] in <filename unknown>:0

  at (wrapper remoting-invoke-with-check) MeGUI.MainForm:.ctor ()
  at MeGUI.MainForm.Main (System.String[] args) [0x00000] in <filename unknown>:0
I don't use 64-bit. And there's only one package (re processor architecture) of MeGUI downloadable. This error had occured with every MeGUI release I've tried so far.

Any help on this?
