Help recovering an older server

[aldo]

Hello!
My office was running on an old OmniVista 4760 running version r4.1.12.00.b. Unfortunately the disk of the server started failing but we managed to backup most of it and lost only a few sectors. While we are planning to move to the new 8770 we need to recover this one first. We recovered windows and the systems is booting up again but it looks like the Omnivista software is corrupted too and we don't have an installation ISO matching the version that we need to repair.
We contacted our reseller but he is also unable to provide such an older version. Does anyone have a backup of that version? Or can anyone point me in the right direction in order to obtain a copy?
Thank you

@alexeik byreading older posts it seems like you have some older versions, would you mind sending me one please?
