Neo Speech not working

I have just installed Adobe Captivate 8 on my PC (64 bit)  I also have installed the Neo Speech program.  I can see all the 'characters' in the folder so I know they have downloaded and installed on my PC.  However when I go to convert text to speech it states that I have not downloaded Neo-speech and I only have 'Anna' has an option.  Is there something else that I can do
