Problem with instalation of unreal datasmith plugin AC28

Hi, I am not able to update or uninstall datasmith exporter for archicad. Wheter I try to do so, this error screen occeurs… I tried to find the installer for older version of datasmith exporter, but couldn´t find it… Do you have any idea how to replace it/update it from my pc (to avoid setting ntb to factory settings). Thanks for anything!
