I was able to download the 2020 version of the software, open a ".DNG" file from my Leica M8 and process it. When I save the file, I had to use a "Save As" and then explicitly navigate to the File Folder that I opened the DNG from. This is under Windows 10.
SO- like many of these programs, it goes to a default and had to be explicitly set to the file folder that I wanted the file saved to.
Hope this helps, I learned that the Corel Product cannot properly open the monochrome DNG files, it tries to interpret it as a color file. It messes up.
Yes thank you for the reply, it's just odd to me that it was saving into my folder's I created for then just changed to not being able to.. documents or any other folder it won't go to, like my photos I use to be able to save them back into my pictures folder but I can't now.. but anyway thank you again for your help.
