Uninstall Datasmith Archicad Exporter Versione 5.4.0

I’m trying to uninstall Datasmith Exporter for Archicad to update new one. It seems to need Unreal

DatasmithArchicadExporter_5_4 (Windows) file in my computer to complete uninstallation, which I had deleted years ago and I cant find this version everywhere else.

Can I ask how to find this version again to uninstall it? Does anyone still have this version? Thank you
