Camera Raw 9.9 is not compatible with Photoshop CS6. The latest version you can use is Camera Raw 9.1.1. If you need support for a newer camera model then you will have to use the latest DNG converter. It's a free download from Adobe, and you can create digital negative copies that include all of the original raw data. Those DNG files can be opened with Camera Raw 9.1.1. You have to check system requirements to make sure the latest DNG converter is compatible with your operating system.
Since you are using Windows 10 there should be no problem using the latest DNG converter. Using the converter is the only way you can get the raw image data from that camera into Camera Raw with Photoshop CS6.
