What worked for me was to look for any melodyne products in the uninstall window and remove them. Reboot, I tried initially not rebooting and it did not work. Once rebooted install and all was working for me.

Yeh, I figured out that it's the exact same set of files (executable, plugin and help) for all editions. I use the same scheme in my own software. What threw me was I expected it to re-read the license when I started it up. Rebooting didn't do the trick for me, though. I had to de-authorize Essential. Only then could it be convinced to run as Studio.
 
All's well that ends well. I've got my familiar Studio back and I can run it from within SONAR. It's fun to drag the mouse around multiple clips and have them all pop up in Melodyne with a single keypress, then render them all at once after editing. No more file transfers, communication VSTs or lost synchronization.
Yup, it was worth the 99 bucks.

Well worth it just for this:
 
With the Sound Editor in Melodyne 4 studio, you can edit the sound of your recordings – just like your music – in a more musical, detailed and inspiring way. From the subtle enhancement of envelopes and timbres to the manipulation of overtones, resynthesis and radical experiments in sound design.
Melodyne recognizes the notes and their overtones – also a decisive advantage when it comes to sound processing. While conventional equalizers only act upon fixed frequencies, Melodyne adapts to the audio material itself. Adjust the level of individual overtones within each track, shape the basic sound of each instrument, relate the timbre or envelope of each note to its pitch, bring out the character of each sound source.
The results are novel acoustically, often unique, invariably invigorating – yet the Sound Editor is intuitive and lends itself easily to creative use.

Been playing with the harmonics editor.  It's fun just watching the harmonic content move about during playback, although I haven't yet been able to implement any significant improvements in vocal tone. "novel" is a good word to describe what I've accomplished so far...

For fun click on randomize spectrum. 

V-Vocal baby yeah!

How do you flatten excessive vibrato using the version bundled with SONAR?

Taming vibrato was one of my favorite features of V-Vocal. For pitch correction Melodyne sounds more transparent, to my ears at least. Has anyone tried using V-Vocal on vibrato either before or after pitch editing a clip with Melodyne? I'm wondering whether it would be worth the trouble of digging out my old SONAR discs just to install V-Vocal. Of course, I could just buy a Melodyne upgrade. . . .

So when I upgrade to Melodyne 4 Editor, I will need to deactivate  Essentials from the Celemony site. and then perform an uninstall of Melodyne Essentials. Then after rebooting the PC, install Melodyne 4 Editor and all should work well?
 
Thanks for doing all of the hard work for me,   I really appreciate the sweat and tears.
 

I did not have to deactivate Essentials, but I did have to uninstall Essentials on Studio A's computer, but not on Studio B's!  Why the difference?  I do not know.  I just installed Studio on both however and was then directed to a new page on their site that showed 2 new activations ready to be activated.  I then activated them.
