I don't know where to start

Always... but literally always, after every update, there is another bug, which most likely occurred in previous versions already. Then it gets fixed, only for another one to appear. Recently, I had false colors in the preview, so I updated to another version (I lost track of which one since I tried several). This problem seems fixed, but now the start script for Photoshop is missing. As a result, I cannot use the image processor. It asks for the latest version of Photoshop, which I already have installed. Alternatively, I tried using the 'export to' command and set up JPEG export in the highest possible quality. Some images now have a green or even a red tint. I don't know where this comes from. It's really like an adventurous journey using Adobe Bridge. Just wondering what comes next. I guess some funny encounters with the output module. Or maybe it even goes missing... again.
