For my DSLR I decided to give the manufacturer supplied software a try (yes, digikam, Rawtherapee, Darkroom etc are fantastic). To my surprise I was able to get the 32bit version to install, and open (the 64 bit wouldn't) via wine. There have since been updates, and for this application, you download the updated zip, extract it, and run the 32/64 bit updater, and your app gets updated. Well, I can get the updater app/file to open under wine, but it doesn't actually update the camera app.
I'm not even sure where to start trouble shooting this. I did a quick google, but that lead no where. Open to all ideas, I'm sure there maybe info you need.
Thanks, Xboxboy
