What OS are you using?
I know there seems to be an issue with getting it to run on Windows 10. I just played it on Windows 7 and had no real issue.

I think there's a patch from Broccoli you need to install. It should be hosted on some forum or the pastebin. Your DirectX also might need an update. There should be an installer in the game folder. Make sure your Applocale is set to Japanese Unicode and the time & settings of your PC is also set to Japanese. If you are using a newer OS without Applocale, you should be able to use Locale Emulator instead. You can download that off github.
You seem to have the correct font, so that should be fine.
I also think you might need to use a different startup icon than the normal one. In the game folder, there should be several different icons with a separate angel on them. Like one has Milfuelle's face, one with Forte's, etc. Try them all.

Some say messing around with 16 and 32 bit options and fullscreen/windowed helps. Try switching them up and then exiting the game, then reopening them with the different options.

Don't feel discouraged. Playing visual novels and 2D games in the 2000s on english PCs was always a challenge. Most older games are a pain to get running. Screwing around with options, patches, ascii, locales, etc. was to be expected
