I installed the EQ. It does not fully scan in the 64bit scanner. The registry entry reports it is not a VST plug-in. I am using a newer scanner than the one in X3 but I would expect a similar result.
It might work with jBridge or the 32bit version of X3, I do not have either installed.
There must be a reason Audiocation did not port the EQ and Comp plug-ins to 64bit but did port the Phase Alignment Tool and Loudness Meter. The Loadness Meter scans and loads OK. May want to ask them about these plug-ings.
Edit: I just noticed the response about email to manufacturer. I was testing and composing this reply at the time.
