WIN 10 DNG CODEC 2.0 does not work with AI Denoised DNG Files (Crashes)

[Yves29732378egnf]

I installed the latest version of Lightroom with IA denoise but the DNG file generated cannot be previewed in WIN10 Explorer with DNG CODEC 2.0 (latest version). It cashes Explorer. Other DNG files from RAW conversions work fine.

I am not able to replicate this.  Enhanced files show as correct thumbnails and previews in Windows 10 Explorer. I do not experience a crash. 

We’ve reviewed the email address you use with this forum and find no crash reports in our system.

Did you see a crash dialog?

Do you use a different email address when filling out the crash report?

Was the crash dialog Adobe’s? Microsoft’s? 

[Yves29732378egnf]

There is no crash report, the Explorer window just shuts down/disappears. The file is visible when in details or list view modes but crashes Explorer when in Icon views. Must be the CODEC but not sure what option I have to fix that.

Based on that I would refer you to Microsoft for further troubleshooting. 
Make sure Windows and Video card are completely up to date...

The Adobe codec isn't necessary to view Enhanced DNG thumbnails in Windows 10 - I don't have the codec installed, and I can see the files perfectly well in Windows Explorer:

Uninstall it? It's simply not needed if Win 10 is reasonably up to date.

[Yves29732378egnf]

Tried uninstall. No success, same situation. Regular converted DNG show fine, but the one generated by AI Denoise bombs Windows explorer in Icon View.

WIN10 is up-to-date. Here is the regular view

Now that I removed the CODEC, the PS sticker shows up. Was not with the CODEC.

The only way I could make it work is to reprocess the Denoised DNG with the DNG converter within LRC. It creates a smaller version of the big Denoised one that behaves like any normal DNG.

What codec did you have installed? A third party codec may have messed things up.

As Keith says, no codec is necessary. Windows displays DNG thumbnails natively.

[Keith Reeder]

"DNG Codec 2.0" appears to be Adobe's own codec - but as we agree, it's entirely redundant.

(It's significant, I imagine, that it hasn't been offered for download by Adobe for a very long time.)

You raise an interesting point though - maybe Yves has other codecs in play as well, such as the FastPictureViewer codec that I used to use when I was still on Win 8.1.
