[ArchiCAD25] - Error at startup, libmmd.dll missing


Hi all, I'm currently struggling with the libmmd.dll error at startup on ArchiCAD25 and the Cineware warning prior to start rendering process saying that Maxon's Cineware add-on crashed and Archicad needs to be restarted.

The library is still missing even after installing the required Intel Redist C++ (as per

I've tried to uninstall single components as well as Archicad itself and reinstall everything from scratch but it didn't help.

On the same machine I'm also using v22 and it's running without any issues and rendering works just fine, is that anything else I can do to fix this error for v25?

I've also tried to copy the dll file from v22 but it doesn't work, any help would be really really appreciated!


Many thanks in advance and kind regards,

Thank you very much for the question and I am very sorry about the issue!


The missing libmmd.dll is part of the Intel C++ Redistributables. Could you please uninstall and reinstall it using the installer found in the article and see if it fixes the issue?


Looking forward to hearing from you!
