Strongly-named assembly is required

I built a gha that has two dependencies. While loading the gha to grasshopper, most rhinos work fine except for one computer. It rejects with the following error

Checking the dependent reference dll ETABsv17 properties, its Strong Name was already set to True. This was shown in the error. PublicKeyToken was not null but indeed contains a number.

Both computer and gha was built on Rhino6SR22. All dlls are unblocked
