Each product of ERA Bundle is an audio plug-in effect, which means that you cannot find them in your applications folder and launch them like a standalone application.
Instead, you need an audio plug-in host, like a DAW (Digital Audio Workstation) or NLE (Non Linear Editor) to open and use the plug-ins.
I don’t have a host! Could you recommend one that would be compatible?
There is a list with all the compatible plug-in hosts and Operating Systems in the ERA Bundle page.
You can also find additional information, for example about the installation procedure or how to load a plug-in in a supported host, in the Accusonus Help Center.
