Trying to load Orca 3d

Hello All,
I bought a new machine and am trying to load Orca 3d (V1.5) from the download.
I get this message:
Orca problem
Is this an issue I can fix, or do I need to contact Orca3d?

The icon in the error dialog does not come from Rhino, and does not look like the Orca 3D logo either. I don’t know who can help, but for Orca questions I’d contact the vendor. Note that Orca 3D 1.5 is for Rhino 5 only, for Rhino 6 and later you need Orca 3D 2.0

Hello Nathan,
Thank you for your reply.
I got this response from Orca3d:

And it worked.
Kind regards,
