Pentax K-S2 PEF files suddenly not recognized.

[annaviviennewilliams]

I have recently purchased the (NON CC) version of Lightroom 6. I have created catalogs and have been working on many photos successfully. Following one of the Adobe "how to" videos, I wanted to try out the Dehaze and realised it's not in the non-cc version, and would have to implement an upgrade or a "plugin" (Prolost). I attempted first to upgrade Adobe Lightroom. Shutting down Lightroom - but when I restarted i got an error saying Lightroom couldn't be found. I re-installed it and now ALL of my photos in Develop come up with "The file is not recognized by the raw format support in Lightroom". All the Develop options are greyed out. I see that the .PEF files from the K-S2 are supported by the Lightroom 6.1 (on page Cameras supported by Camera Raw ) but don't understand why I have happily been using LR6 for a few weeks fine with photos from my KS-2.

Please can someone help??

thank you very much

What version Adobe Camera RAW in "About"? Has to be 9.1 (newest is 9.10.1)  Camera Raw installer for Adobe Photoshop CC and CS6

Camera Raw is hard coded into Lightroom, so the Camera Raw installer will not work - it's a plugin for Photoshop.

annaviviennewilliams - when you reinstalled Lightroom, the base version (6.0) was installed, so you need to update it.

If Help > Updates doesn't work, download the update from here (6.10.1 is the latest version): Download Photoshop Lightroom

Thanks Per Berntsen​. I'll try that . For the moment - since I'm just beginning and trying out Lightroom, I've converted my photos from PEF to DNG and reimported them. That works... but I was so despondent to see that all the work I'd done on the previous uploads couldn't be used. 😞

I don't understand why lightroom was working perfectly and suddenly - not updating Lightroom triggered the rejection of previously accepted format?

This happened because reinstalling always installs the base version (6.0), which does not have built-in support for your camera.

So you need to update to at least 6.1 to get support for your camera.

Many thanks- this has worked for me. Appreciate your input on this! Has restored my faith in LR!
