PSCS5.1 can't open a DNG

[hening]

Hi!

I have installed PS 5.1 on my MacBook running OS 10.9.5. It can not open a DNG from a CR2. I thought the CameraRaw plug-in might be missing, downloaded the Application Manager, then CR 6.7. But got the message "This patch is not applicable for you." The Help menu of Photoshop tells me that my software is up to date. What is going on?

Apart from that - Merry Christmas!

Hi Kglad! Thank you for answering. But as I wrote, the PS Help > Software update says my software is up to date. PS is 12.0.4. Furthermore, Bridge crashes on launch. I just don't understand.
