OM 7.2 Windows 11

Dear Karim,

I have been helping a student to install OM 7.2. We have two issues that I couldn’t solve:

1- When I try to put a sound into a patch using different methods (drop-in/ load through file-chooser/ or evaluate a sound box), I receive an error message. On the other hand, when I synthesize a sound through OMChroma, it creates the Csound files but again gives the same error message for the sound and doesn’t create the sound file. Could you please assist? I have attached the screenshot.

2-Eventhough if I chose the presentation mode “list” in the preferences. The patches, or subfolders appear as icons, stacked on each other. What could be the reason?

Thank you in advance.
