From my limited japanese, it seems the errors says it cannot find some files. my guess is there's maybe a locale issue where it installed shift-jis files with incorrect filenames or something.
If you change the locale make sure to reinstall the entire software as it might have named files improperly if it got installed with another locale
Thank you for the detailed instructions. I'll try them out in a few days when I'm home again ^^mm..if you're using Windows 10 (but from the screenshot seems like Windows 11,should be very similar) to completely change the locale, you have to change to Japanese language in the Settings app but also in the old good Control Panel, go to Clock and Region, click on Region, then select the Administrative tab and the second option should be the one the change the locale "Language for non Unicode programs". A restart of the PC is needed
as SeleDreams said, you need to uninstall and install again because of that, and you should also check in the Settings app -> Time & Language that you have installed the japanese language pack and also the speech recognition data, and maybe you should set your keyboard to japanese. I don't have Flower, but sometimes even a not-JP set keyboard might bring some issues, so you can try that. You can use your DE keyboard and basically change it from Windows as a JP keyboard, you'll have the IME editor too to type in romaji/kanji, and you can always go back to German language for keyboard and system locale from the Settings page and Control Panel
edit: also, run the .exe as administrator (right click, choose run as administrator) and set your time zone to Japan (Settings-Date & time - time zone UTC+09:00)
there are even some programs (such as Internet Co's ABILITY daw) that won't even run unless the windows display language itself is set to japanese, even if the locale is properly set to japanesemm..if you're using Windows 10 (but from the screenshot seems like Windows 11,should be very similar) to completely change the locale, you have to change to Japanese language in the Settings app but also in the old good Control Panel, go to Clock and Region, click on Region, then select the Administrative tab and the second option should be the one the change the locale "Language for non Unicode programs".
