Why isn't my P5 Spectral Transformer available anymore?

You need to check that the "Shared Plugins" folder is in the VST search path in Sonar.

Lots of name truncations there. I'm assuming you mean you mean the new Sonar Professional. Sometimes even after pointing Sonar's VST scanner (which it sounds like you have done) you still need to do an FX browser refresh. I haven't done this in ages but I think you need to be in the correct directory in the Browser and hit F5.
 
I've only needed to do this to find new drum patches and the like and as I said it has been a while.

Thanks. I tried that earlier today, but will go back and do it again. The installer  for P5 and SPro recognizes that my 'Shared Plugins' is on my E: drive and that's where the files got sent. I'm surprised that I'd manually have to list that to the VST scanner, but did try that (and also the Shared DXI, just in case).  The scanner seemed to find the other FX's located in the Shared Plugins OK. Some get labled as Project5 plugs like the SpecTrans, others don't, so I look through the list of found items pretty carefully. I'll try it again and report results. It wouldn't be the first time I'd done something 'wrong'.

Edit add. info.:  Confirmed...  P5 plugs show in SONAR x64(bit) but not in SONAR x86(32bit).

Don't you mean the other way around?

Thanks for the fdbk as I try to sort things out. I could've sworn that I'd seen my Project5 Spectal Transformer show up in some version of Sonar recently, but being unable to reproduce it at will, I was reluctant to report it. Some of the fog seems to be lifting, though the path forward still seems a bit murky. This is also why I'm also asking questions about the 32b installs, bridging, DXI's etc. 
 
I'm almost beginning to think I might have to actually install a 32b Win (Vista maybe?) in a VirtualBox to just get some of the god-forsaken DXIs (that apparently don't bridge, again not noted in the upgrade doc's) updated and converted to VSTs. I'll have to think really hard about that one, as a bunch of stuff is just becoming an orphan that I'm not going to deal with. Of course, those projects also get trashed and it leaves me wondering about what to include or not in existing projects.
 
I'm still a bit confused about some of this. For instance, my Pysn-II (DXI) from P5 seems to work OK. I've already converted it to a VST as well, but that one can't find its presets, so may need some more attention.
 
It seems like some stuff relocated OK, but others didn't. More surprises, I hate when that happens. But I shall remain calm and visit my library (with the books and stuff) shortly.
 
 

Is there a list that I can refer to that I can check things off on?
 

This is my first dance with the Sonar 64b bit stuff as my old Vista/32 box was pretty trouble-free until it died of old age. So, I'd moved to Win8_x64 on my laptop over a year ago to get hold of the ropes, but didn't install much music stuff, and certainly not Sonar. This probably accounts for some of my 'learning experiences' as I go about the new installation to the best of my abilities. I'd hoped to just get back to where I was, with maybe some new enhancements. I'm making progress, but only on the installation, not playing with the tool itself. Just a comment as it seems a pretty difficult transition so far.
 
 

Thanks for clearing that up. My post #9 was in response to the edit added to post #7 and post #8. It was not meant to suggest anything WRT the Spectral Transformer.
