Apple is making it harder and harder to support 32-bit applications, and so are various 3rd party frameworks we are relying upon. In order not to limit the 64-bit application, we thus made the decision to drop the 32-bit applications on macOS. I hope you can understand this decision.
From my perspective this is perfectly reasonable and understandable. Is it Mojave, or the next one will not support any 32bit apps period. so it is what is it.
I also was using the 32bit server occasionally, but truly there are only a couple of plugins left that are ever an issue and frankly there are not 64 bit alternatives and I'd rather be done with the fiddling around.
Just checked and it's Mojave that is the last OSX to support 32 bit plugins. It's important to me that 32 bit continue because there's a couple of plugins that I use (NI's B4-II and Pro53) that are 32 bit only and I make use of those on a regular basis.
Either way around I'm back on VEPro 6. Would have been great with VEPro 7 but it just wasn't in the cards.
