IBInstall Component

I'm having a problem everytime that I try to use the TIBInstall component.
When I execute this statement:
    IBInstall.MsgFilePath := IBInstall.SourceDirectory + '\interbase.msg';
An error is generated saying:
    'Messages file ibinstall.msg found is invalid. Can not load'

The full path that I assign is:
    'E:\Projects\InSight\IB Installer\interbase\interbase.msg'

I've traced into the VCL source, but am unable to find where the value is
getting changed from "interbase.msg" to "ibinstall.msg" and is that the only
problem

Any ideas?
