Plugin won´t work in 3dsmax 2024

Hi the D5 plugin apparently installed in 3dsmax 2024 (Win 11) but the Menu entry is not there. When tying to load the plugin manual from the plugin manager, got this prompt:
“The following DLL will not be loaded because it doesn´t implement the functions listed below:
C:\Program Files\Autodesk\3dsMax 2024\Plugins\D5Plugin.dll
-LibVersionç-LibDescription
-LibNumberClasses
-LibClassDesc
To fix this, implement the missing functions”

How can I do that? 3dsMax works fine so far. Thanks for your help.

Hi @reyner2305
To display the plugin after installation, please navigate to Customize->Customize User Interface Menu Editor. Search for D5, and drag it out. Thank you
