Backpeddle - new projects in X3D don't even have any V-Vocal option which suggests it is not installed, old projects give me the option and the crash.
 
Above I wrote wrong so crossed it out...
 
@Clint please create a new project, can you confirm that a crash doesn't happen, it's only old projects?
 
UPDATE - Seems I can no longer reproduce, it must happen under specific conditions, but as you can see on my previous post it does happen. Use Melodyne ! :)

Vvocal still crashes the program for me, every time.  Tried re-installing from X2, etc., nothing worked.  Any help?

If it crashes immediately on creating a vvocal clip then most likely you have a broken install.  (especially if the same crash occurs in X2)
 
Look in C:\Program Files\Cakewalk\Shared DXi\VVocal
You should see:
Cronus.dll
VpEnc.dll
VPSoloDec.dll
 
Also there should be a subfolder called Skin which contains 4 bitmaps and 2 ini files. If any are missing its possible that one of these is causing the crash.

Well Vvocal works for me but occasionally crashes.
DLL versions are:
 
Cronus.dll 1.5.2.5
VpEnc.dll 1.3.0.0
VPSoloDec.dll 1.0.0.2
 
Hmm wondering if renaming those .INI files does anything.... Hey kids don't try this at home...

All of the above are installed, same version #'s.  Always worked in X1 & 2, though I haven't tried them recently.

I have an old project which I'm attempting to finish and every time I start V-Vocal I get a fatal crash
 
It's fine on new projects so i guess I have some investigating to do

I never bounce V-Vocal or Melodyne unless I need to further mangle the audio. I'm sure I've had at least eight simultaneously running instances of V-Vocal (meaning actually playing at the same time) even on my previous home-built system.
Never noticed any crashes because of it, if they happened they seemed to always be upon first insertion.

It's the elimination of crash upon first insertion that prompted me to start this thread. However, I have not opened pre-X3d projects where the crashing happened before to see if the crashing still happens with those projects. As the problems happened for me when Take Lanes were involved (which got s lot of use for comping vocals), I suspect the change in Take Lanes in X3d might be the reason why I no longer have problems.

Hmmm I dont have any pre-x3 files with v-vocal.
