Using V-vocal in X3

You may need to re-install it with a "custom install" of X2 or earlier. Just select V-Vocal from the things you want to install.
 
Note - I have 8.5 > Sonar 2015 installed and I never had to do anything extra to ensure V-Vocal was available in the X3 or Xplat versions... but if a VST/Plugin refresh doesn't magically bring it back, try the re-install technique.

V-Vocal is a DirectX plug-in, pointing the VST scanner to the folder is not a good idea. VST reset/rescan also will not help for the same reason. If V-Vocal needs to be reinstalled, there is no separate check box for the plug-in in the advanced install checklist. Reinstalling V-Vocal is part of the SONAR executable installation, the first check box in the checklist.

Thanks....I thought I could use the info about it being a DirectX plugin, but what I tried did not work.  Background:  When I was using X1, I was using Windows XP (32 bit).  Then I installed a new drive with Windows 7, so I installed X3 as 64 bit.
 
After your suggestion, I noticed that the V-Vocal dlls were showing up as files in Shared DXI folder under Cakewalk under Program Files (x86), but not under Program Files>Shared DXI (the 64 bit folder), so I copied them over, so they are there but X3 still does not find them.
 
I have done a reinstallation of the full X! program, although this was after I already had X3 installed on this new drive.  I wonder if this could make a difference. Would it make a difference if I did a reinstallation of X3?  Or is there anything else I can do?

Thanks much!  I had not seen that info about needing to install the 64 bit version before.  And I followed the rest of your directions.  Now it works!
