VST3 from old to new workstation is missing


I’m using Ardour6.9 on W10 on my old laptop, now I’m moving to a different machine, installed ardour on it (same installation file 6.9.0)

created the folder:

C:\Program Files\Common Files\VST3

and copied there my file as I did on the old laptop, here I stop because there’s no way to load it, here below the screenshots of VST options on old and new machine[Processing:

Thanks for your time.

Perhaps 32/64bit mismatch?

This is an old style VST3 plugin that is not in a multi-arch bundle, so from the screenshot is not obvious if it is a 32 or 64 bit VST plugin.

Which version of Ardour do you use (Menu > Help > About)? 32 or 64bit?
64bit Ardour can only load 64bit VSTs.

Yep I forgot to mention, 64bits for everything, from OS to VST file.
