2021.2 upgrade from 2017.  No one on any workstation NOR the server can run an Aatrix form.  (Any form).  I have uninstalled, reinstalled, installed for the first time where no one had ever accessed payroll before, manually updated from Aatrix's website.  I have compared the ProgramData/Sage folders and copied over missing files, ditto the Aatrix folder.  Still no luck.  Sage error on KB is similar, but not exactly the same.

Help, please!
