This really frustrating as it took a while to arrange for the cross grade purchase. I had tried the demo, and it was working for me. I then installed the non-demo version, and it won't work for me. I have uninstalled all of it multiple times and reinstalled as many, but it fails on "Adding VST3 Plug-in Active Equalizer". I have opened a ticket with support, but for goodness sake - it should work and it's not. Any suggestions?

No answers on this thread - I did get an answer from Studio One Support - and I've decided to clean out all my vsts and reinstall them. I have cruft from a lot of old installs, and I'm pretty sure that some 32 bit plugs might have snuck into the 64 bit areas, so reinstall and be very disciplined about where to put the plugs. Hopefully, that will help my new DAWs find them and help the plugs to work.

VSTs can be a pain for this sort of thing. Cubase actually has a quarantine system built in to block VSTs that are known to cause issues, which is actually a good idea as it means you don't get loads of complaints about your software crashing when it is actually a plugin causing it to crash. In Sonar, for example, I found that most crashes were caused either by soundcard drivers or VSTs. So in other words, 3rd party software and not Sonar. Yet people normally blamed Sonar.

Thanks for the reply, 35mm. What I'm really considering now is uninstalling all my plugs and then reinstalling only what I want, being sure that there are no instances of 32bit plugs installed. That way (since I've been on 64 bit only for a while) I can be sure there are NO 32 bit plugs installed and that the cruft from years of installs is eliminated. What do YOU think about this (or anyone else who has an opinion/experience to share)?

The default folder for 64-bit VST3 plugins is:
 
C:\Program Files\Common\VST3
 
That's where Studio One looks. You don't need to add that folder to the search list. Any VST3 plugins installed anywhere else will not be found.

That's true, but like with SONAR you add folders for it to look in. 
 
I think a VST purge is a great idea.  I do it every few years.  And something I swore off of was free plugins in general.  Some are great, but some are dawgs.  And the dawgs will cause you no end of problems.

Soooooooo true.  A few years ago I was having crashes like crazy and cussed SONAR daily.  Turns out it was my sound card.  Upgraded to an RME and it's been smooth sailing ever since.

A good clear out once in a while is always a good idea. Many of us have huge piles of plugins, many we got free or for some special offer and many of those only ever get used once if at all. So yea, just install what you want, but keep a catalog of all the plugs you have that can be installed if you need in future. Often, having fewer great tools is better than having loads of mediocre tools and having fewer plugins reduces the chance of instability and random crashes. But you don't have to completely forget about the 32bit plugs if your DAW supports them and if they are useful to you still. You can install them in a separate VST folder and either have that folder loaded in your DAW or not. Most DAWs support multiple VST paths, so you can also split your whole collection up if you want for better management.

Actually Studio One has a kind of "quarantine system" for VST2 and VST3 as well. Plug-ins that crashed when first scanned are moved to a black-list. On the next launch, the scan will skip the bad plug-in. The blacklist can be reset in Preferences>Locations>VST Plug-ins. It often helps to just reset the blacklist so the quarantined plug-ins are scanned the next time you launch Studio One. Alternatively, you can try to remove the plug-in from the VST plug-in folder and add them again after the first scan.
