Peter, I was not clear in my last msg - sorry. Sony says some 32-bit applications will not run on the Vista 64 bit OS. Music Creator 5 apparently will install on Vista 64, but as a 32-bit application. I want to get Music Creator 5 because it is the least expensive way to get TTS-1, since you can't buy it separately. So I am trying to find anyone who has installed Music Creator 5 and got it to work so they could get TTS into their 64-bit system. Have you installed Music Creator 5 on a 64-bit system and gotten TTS that way or can you otherwise confirm for me that it can be installed and be operative on a 64-bit system so that I may access TTS? Thanks for your patience with me! Scott
