The older version of unreal datasmith exporter for 3ds max cannot be removed

For six months I have been trying to install a new version of the Datasmith program. I searched the internet for ways to solve this problem. But nothing helps.
I cleaned the registry.
I actually tried this program and it did not show up datasmith in the list.
