stereoexpander fx

opening an oild project i see that an fx, STEREOEXPANDER is missing
I think it was a Steinberg plugin, a built in one. Is it possible to get it somewhere?
thank you

if it is a Steinberg plugin it will be 32 bit and maybe found on a very old install image of Cubase

i should have done thta may be 5 of 6 years ago…what version shall i look for in your opinion?
