Need someone to convert a compressed DNG to TIFF

Hey Folks,
looking for someone with access to Adobes Software to gain access to an old compressed DNG. Because of my move to linux/darktable I can unfortunately no longer open the image and would like to polish up a photo of someone near and dear who died this week.

your help would be greatly appreciated.

Edit: solved the Problem with lightroom mobile now

I could open it in non-Foss FastRawViewer under Windows 7 and the review image looked OK … but FastRawViewer can not export as TIFF.

Non-FOSS RawDigger can export as TIFF but was overbright:

DSC01756-RGB.tif (69.7 MB)

Best I can do on my Adobe-free computer …

Neither ImageMagic nor fotocx will open it.

Forgot to mention that the Adobe DNG Converter can open a DNG of one kind and save it as another kind but still DNG, if I recall correctly …

An example of that are “linear” DNGs which can not be opened by all editors but can be converted to “ordinary” DNGs and then opened by almost all editors.

Thanks for your help @all!

[IFD0]          DNGVersion                      : 1.7.0.0
[IFD0]          DNGBackwardVersion              : 1.7.0.0
[SubIFD]        Compression                     : JPEG XL

As already mentioned, just put it through Adobe DNG converter and make sure it writes a DNG that is compatible w/ versions earlier than 1.7 (and/or do the same when exporting from Lightroom etc.).

And also Adobe DNG Converter works on Linux with Wine.
