HeyRed.Mime.MagicException: Could not find any valid magic files! on Windows Server 2012 R2 when program is on path with ů

[janseris]

Hi, on Windows 11 on two machines and Microsoft Windows Server 2019 Standard
10.0.17763 N/A Build 17763, it works fine.
However on Windows Server 2012 R2, it reports:

HeyRed.Mime.MagicException: Could not find any valid magic files!

I did not install anything manual on the Windows 11 machines.
The application is distributed using MSI installer x64.

Magic files are present (I cut the folder path to show relative path):

Do you please have any idea why?

Edit: I noticed that if I change instalation path to C:/ instead of C:/Program Files/path with spaces and symbols like ů, it works correctly.
Edit2: removing the symbol ů from path helped. It works correctly on newer machines, though, regardless of path.
