Please Help otherwise i have to reinstall the hole PC ;(
Hello,I have this problem too, have you found the solution?
which version do you need to uninstall? @Fuarks
Hello,
If you still have the issue, try clean desinstalling Datasmith and all that is related to it with this utility program:
and do a fresh install afterwards.
Hallo…
I have a similar problem too. Hello, I installed the updated twinmotion 2024.1 and 3ds Max 2025 on my computer. However, I’m having trouble trying to install UnrealDatasmithMaxExporter_5_4_1. I can’t install it because an older version is installed, or there is another reason. The problem is that I cannot uninstall the installed UnrealDatasmithMaxExporter_5_0_1 version using add or remove programs. In this case, I tried almost everything written in the forum, but I could not solve my problem. I need help.
Run this MSI to uninstall the 5_0_1. Then you can install the 5.4.1
