Hi Dave-

Thanks for posting your workaround. What version of OSX are you running? Does your user account have write access to the AAX plug-ins folder (you can check by right clicking the folder and clicking "Get Info")?

Running the installers for the plug-ins here, without an Eventide subfolder, still creates and places the plug-ins in the subfolders successfully. However, we're seeing multiple reports of this and want to track down the issue.
