When I run the vital installation and add it to FL Studio, the plugin is added to the list correctly, but opening it simply replaces the plugin content with a screenshot of the fl studio screen. However, it can load sounds made from other projects. Trying to close or export with the plugin crashes FL Studio. I tried installing it yesterday, the plugin worked. However, the day after, it broke, and installing again didn’t work, even with completely uninstalling the plugin beforehand. Opening the application works.
is this on Windows?
Yes, it is
Sounds like an issue with graphics drivers honestly - wouldn’t hurt to try to check if there’s an update or reinstall them completely.
You could also try to run FL Studio in “Scaled” mode, default location is:
C:\Program Files\Image-Line\FL Studio 20\FL (scaled).exe
If this doesn’t work check out if other DAW runs Vital properly - you can try to download Reaper for that.
If it does not work only in FL Studio you could give a go to messing with wrapper settings or trying to run it as bridged.
Hope this helps!
