Do you have at least one ASIO audio device in your system?
Typically, the onboard audio device in your computer isn't and will not work with PTF.

Are you an administrator on your system? You may want to uninstall PTF and reboot your system. When it comes back up, right click on the PTF installer and choose Run as administrator.

Lastly, you can try holding down the N key while PTF loads, which should bring up the playback engine dialog; allowing you to choose the audio device for PTF.

Another thing to note is that some audio devices do not like to be shared between Windows and PTF. You should set Windows to not use the audio device you are trying to use for PTF.
