Photoshop CS5 cannot open new NEF files

[helgab33]

My old Photoshop version (CS5) is running on a Windows Computer. In the meantime I have bought a new Nikon camera D5600, downloaded the latest camera raw plug in version 9.9. However now Photoshop cannot open the new NEF files. I suspect that I will have to upgrade to the latest version but will this be compatible with Windows 7 or will I need to upgrade to Windows 10 first? Also is the latest version of Photoshop backward compatible with my old NEF files?

You can convert your D5600 raw files to dng to work on in your current version of Photoshop. CS5 stopped Camera Raw at 6.7 You can't install 9.9

It's best you get up to date. So much has changed since CS5, and CC 2017 works with all your raws, past and present.

Camera Raw 9.9 will not install on CS5, the latest version that works with CS5 is version 6.6.

Your camera requires version 9.8, so you have two options:

• Subscribe to Photoshop CC. The Photography Plan, which includes Photoshop and Lightroom, is $10 a month, annual commitment. You can also subscribe to Photoshop only, but it's twice as expensive as the Photography Plan.
  And yes, Photoshop CC works with Windows 7, and is backwards compatible with old NEF files.
• Use the free Adobe DNG converter to convert your NEF files to DNG files that can be read by CS5.
  You will have to set Compatibility to Camera Raw 6.6 and later in the converter preferences.
