Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I understand how frustrating it must be to be passed from one person to another.
I think I can say, the buck stops here. I will see if I can advise you through the difficulty and give you good information too.
First I will have to understand just what is going on, though. Are you trying to
1. shoot photos with the new Sony camera, in RAW format?
2. and then, use those RAW photo files, taken by the new Sony camera, in a RAW converter to some other format?
3. and what file for the new Sony camera have you tried and failed to get working on the Windows 7 PC? is it a driver for the PC to interface with the camera?
Let me know, using the Reply To Expert function, and I will advise you as to a way out of the difficulty.
