I went thru the auto install for entire Platinum upgrade.
Including the AD part with 3 AD paks.  Went really slick, or I thought.
 
I am trying to use the AD2 as VSTi and either cannot find, or did not
install this part.
 
64 bit install.  And AD2.exe is there and works well.
 
I did put question into XLN folks also.
 
Thank you in advance!

- Does it appear in Utilities > Cakewalk Plugin Manager under VST Instruments?
- If not, does the .dll appear in C:\Program Files\Cakewalk\Vstplugins?
- If not, the VSTi didn't get installed or is in a non-standard path that you might need to find and add to Plugin Manager's scan paths (Options button).

Open the XLN online installer, click advanced then you will see tabs for 32 bit and 64 bit vst paths, you can either add the path its installed to to cakewalks list or move them to the cakewalk vst folder from the online installer :D

Bam  "the .dll appear in C:\Program Files\Cakewalk\Vstplugins?" It is here
 
Forgot this step in the search...Scroll down the "Darn" screen.
 
I thank you for the help.
