Hi Dave,
We've had a couple reports of this, but we're still working to run down what, exactly, is causing this error on some peoples machines. It doesn't appear to affect the functionality at all, and my understanding is that if you create an Eventide folder in your plug-ins folder before running the installer you shouldn't see the error. Please let us know if this is not the case, or if this is still causing problems for you.
Thanks,
Dan
