Anything related to the old directory structure at run-time will be updated by the updated PATH environment variable. When you upgrade, the installer adds the following entry:
C:\Program Files\iNTERFACEWARE\Iguana
You must restart Iguana and client executables to pick up the changes.
If the path is not updated then you will receive an error when client executables are run (either in the log if Iguana starts or in the application). The error will be similar to the one shown below:
Unhandled Exception: System.DllNotFoundException: Unable to load DLL (IGC).
