Hi,

I did the new update that is avaiable on the website, but then when I select the plane --> library ---> 3d presets ---> Chose the library.

Hi,

I'm sorry to hear you're facing these troubles. Please, check if there is the ForestQtCatalog.dll and/or the ForestQt.dll file(s) in your Max root folder (by default C:\Program Files\Autodesk\3ds Max 2022). If present, close the 3ds max and delete both files. That should fix it.

Best regards,

What are these libraries responsible for? Isn't some other function at FP going to change?

ForestQt.dll handles multiple functions (Qt Dialogs, Forest Lister, etc.). ForestQtCatalog.dll only manages the Library Browser.

The problem with these DLLs, is that in older releases were installed in the Max root folder. Now, everything is installed at C:\ProgramData\Autodesk\ApplicationPlugins.
When a new Forest is installed using the setup program, it calls to the uninstaller of the previous version. This uninstaller is responsible to delete old DLLs from the Max folder.
But if these files are copied manually (some customers have custom installations), they may be not deleted by the uninstaller, causing the conflict.

The solution is to force a DLL removal of old files in the installer, not in the uninstaller. This is in our to-do list for next updates.
