deleting old tts voices NOT in control panel

I installed software that uses the old Microsoft Mary and Mike voices. They were installed (or partially installed), but they don't appear in the control panel, tts, so how do I delete them. If the steps would be different for win7 32 bit and 64 bit, please let me know.

I'm answering my own question. Although these old voices don't show in the control panel, I did a registry search, and there they were! For some reason a search for "mary" didn't work, but a search for "mike" found where they were located.
