Premiere Elements 13 on what computer operating system?
What are you trying to update? There should be nothing to update. There is no update to 13, like 13.1. And, the program should come with Camera Raw 8.6 which I believe is the latest version of Camera Raw.
Your Sony HDR HC7 appears to be a miniDV camcorder. Premiere Elements 13 no longer offers DV and HDV Capture. Adobe document suggests a workaround if you are interested.
Please review and consider and then me know if I have targeted the question that you asked.
