Hello Everyone, I'm currently struggling with the "libmmd.dll" error at startup on ArchiCAD26 EDU. I have contacted my local support regarding Archicad but they didn't know how to resolve the problem either so that's the reason for the post. I have uninstalled and reinstalled Archicad from scratch multiple times. This did not resolve the issue. After that, I proceeded to uninstall and reinstall Cinema 4D. This ended up not working either. Link: "https://Graphisoft.com/downloads/addons/cinema_4d/cinema4d_download"
After further research, I stumbled across a post about this issue with a previous version of Archicad.
I installed all the Archicad 25 additional software, and didn't reinstall it but used the "repair" function which checked the software and repaired it. I proceeded to launch Archicad 26 and it worked fine after. The issue of the libmmd.ddl missing was resolved. I assume it was an issue with one of the software that was installed prior.
