Msi for older Datasmith 3ds max exporters

I cannot install the latest Datamsith exporter plugin for 3ds max because the installer can’t install without me uninstalling previous versions of
the plugin that I have installed.

I am unable to uninstall these plugins
Versions & because the windows uninstall process requires me to have the original .MSI files that were used to install them.

Therefore I need them to be able to uninstall the previous versions so that I can install the latest exporter.

Can someone tell me how I can obtain these please ?because without them I can no longer use Datasmith.


No-one from epic games or otherwise

Just want to be able to uninstall in older Datamsith versions so I can install the new in one?
