Hi everyone,

New here. Hope you're all doing well. I'm trying to install QuadRemesher script in 3ds 2025 and i'm getting this error.

Please help me to solve this issue. Thanks in advance and take care.

You should write the developer of the script for help. It's likely a flaw in their code and not a Max issue.

Check if the QuadRemesher.mcr is in the path shown in the error message. The installer tries to load the file, but it fails, most probably because the QuadRemesher.mcr is not where it has to be. Usually the .mcr files are loaded by the installer after everything else is installed, so I guess that the script is installed properly but its installer can't load the macro.

You can go to the folder where the QuadRemesher.mcr is located and drag and drop the QuadRemesher.mcr onto 3ds max viewports. Then check if the macro is installed.

This script file is in .mzp not in .mcr. Can it be converted to .mcr somehow?

No, do not try to convert it. You can't. When you run the MZP file it starts the installation. During this installation the installer tries to load the QuadRemesher.mcr file. This file is used(usually) to create a category in Customize User Interface, so you can go to that category and assign a hotkey or create a toolbar button for the Quad Remesher tool.

The error message you have posted in your first post shows that the installer of the Quad Remesher tool can't load the QuadRemesher.mcr file. The path to the QuadRemesher.mcr file is shown in your image. Go to that folder(it is a hidden folder) and if the QuadRemesher.mcr file is there just drag and drop it onto any 3ds max viewport. Then restart 3ds max(just in case), go to Customize - Customize User Interface - QuadRemesher categry(or something similar, you can check it by reading the QuadRemesher.mcr file) and you should see the Quad Remesher in the list, so you can create a toolbar button for it.

If the QuadRemesher.mcr file is not there(check the path to it) then either the installer(.MZP file) is corrupt, or the installer can't copy the QuadRemesher.mcr in required folder.

Yes, I did unhide that folder. Even after several attempts there's no quadremesher.mcr file there.

Something is wrong with the mzp installer. If you have a folder for QuadRemesher, then you can unzip the mzp file and can drag and drop the QuadRemesher.mcr onto 3ds max to install it. But, if all other files are not installed properly this will not work. You will have a QuadRemesher macro but it will do nothing.

The other big thing to check is that your version of the script is compatible with your 3ds Max version. If the script was written for Max 2024, it may not work with 2025.

Does modifying the script inside works? If so, how?
