Neo Speech voices not installing in 5.5.

Question

Have tried several times unsuccessfully to install Neo Speech (Kate + Paul) in Cp 5.5.  I am not clear exactly which folder with 5.5 these should be directed to when running the .exe file, which could be the problem.  Some attempts result in the following error message:
a problem occured whle extracting some files.  check availalble space on your computer and the write privileges on the destination folder.
Any suggestions would be much appreciated.

I'm running a 32 bit system here, so perhaps this situatoin is different.  Pointing the Neospeech install to the Cp 5.5 just doesn't seem to work, which leads me to believe that that they're not installing in the correct location.   When I launch Cp there is nothing available but Microsoft Anna, and no other voices visible in Speech Management. 
In 5.0 the Kate and Paul voices are in the VT folder in the main Cp folder.  Copying this to 5.5 does not work either.
Tried reinstalling Cp 5.5 this morning, which was did not change anything.  Never had any problems installing the voices in previous versions, so this is quite frustrating.
Given the Kate voice is used in most of my projects, I may have to stick with 5.0 for now.  Burning up way too much time troubleshooting this.
