Thanks for your suggestions all. This is what I have done so far:
I have downloaded each of the items on the downloads page and 'extracted' them as indicated by the prompts. I have tried to install the NeoSpeech voices again and again, without success. These are all the folders and files I now have:
- Adobe Captivate 7
- Adoibe eLearning Assets
- Cp7_win_assets_installer
- Cp7_win64_voices_installer
- NeoSpeech Voices (64 Bit)
- Captivate_7_x64_Neo_Content_LS21.7z (and 'application' by the same file name)
Please tell me what I need to do to to be able to use the NeoSpeech voices. At the moment, only a Microsoft voice is available in the TTS function.
