I purchased a sound patch for my nautilus88.
I downloaded the patch from korg website. I unzipped the files, copied them on a usbkey. And plugged it on the nautilus. All the files then appear on the nautilus screen. Until then, everything's ok.
But when I select the installation file and process the installation : it says : installation failed. So I did it several times, I also re-downloaded files from korg site again. Same result.
The patch is : KApro : EXs24 Revolutionary Dimensional Cello
I have window 11 on my computer.
Did you encounter the same problem ?

Thanks.
