Datasmith 4.24 for max 19 install problem

I can’t solve this installation problem. Can anyone help me to install Datasmith 4.24 for max 19 please? I also have the same message to uninstall version 4.22. Thank you.

For some reason, MSI that are needed are missing on your system. The way to clean this up is by editing the registry to clean up any remaining bits of older datasmith installs.

  1. go in add remove programs and uninstall datasmith for max from that dialog:
  1. in regedit search for “Unreal Datasmith Exporter for 3ds Max” entry and delete it:
  1. clean up any 3ds max install you may have where datasmith plugin might still exists:
  1. download the latest datasmith plugin installer from Datasmith Exporter Plugins - Unreal Engine

That now should work normally


Hi Pierre
unfortunately I also get that message by uninstalling it. I tried to delete manually but many files cannot be deleted. I need the file it asks for. I really tried other methods besides your method but without success. Would it be possible to have the file requested by the message please? Thank you.

Here you go:

I have exactly the same problem but it is asking for UnrealDatasmithMaxExporter_4_22_E2.msi
Why is doing this??
Were can I find that file so I can uninstall and re install the latest Data smith plugin for 3D Max?

guys, sorry to revive this topic, but I have the same problem however in DataSmith version 4.24.2

Would any of you have this file? Thank you so much.

Thanks a lot. It solved my problem
