How to install Voices in Captivate 2019? The “automatic” way isn’t working!

I’ve now installed/uninstalled/reinstalled Captivate 2019 5 times in an effort to get text-to-speech working with the non-Microsoft voices that are in my Captivate 9 project.  Keep getting the message that the voices are NOT installed, even though I’ve gone through the installed AND copied file directories in multiple places.  Now what?  I’m late for a deadline and ready to call Captivate 2019 a non-starter going forward.   Yes, I’m a licensed user; Yes, I’m signed in.
