Libmmd.dll Missing or Not Found: 5 Ways to Download the DLL

The libmmd.dll file, developed by Intel, is a multi-threaded dynamic math library for the Windows ecosystem and is used by several programs. When it’s not found, or you have an incorrect version of the file, a missing DLL error message pops up.

Sometimes, you also get The procedure entry point _libm_sse2_cbrt could not be located in the link library libmmd.dll error.

Before you proceed, reboot the PC, install all pending Windows and software updates, and remove any recently added programs that could conflict with the OS. For most, these basic checks should fix things!

What can I do when libmmd.dll is missing?

1. Manually copy the DLL to System32

Your primary approach when encountering the libmmd.dll was not found C4D (Cinema 4D) error should be to manually move a copy of the file to the System32 folder. Remember to get the x86 version of the DLL for 32-bit Windows and the x64 version for 64-bit Windows.

For Cinema4D, libmmd.dll is found in: C:\Program Files\MAXON\Cinema 4D\resource\libs\win64

It has to be moved to: C:\Windows\System32

Once done moving the DLL, restart the PC to apply the changes, and the affected program (including Cinema 4D) should work fine!

2. Run the affected program as an administrator

1. Right-click on the affected program’s launcher (.exe file), and select Properties.
2. Go to the Compatibility tab, and tick the checkbox for Run this program as an administrator.
3. Click Apply and OK to save the changes.
4. Finally, restart the computer and verify whether the Cineware libmmd.dll missing error is fixed.

3. Download Intel C++ Compiler

1. Go to Intel’s official website, and then download the Intel oneAPI DPC++/C++ Compiler setup.
2. Next, run the setup and follow the on-screen instructions to complete the installation process.

If a quick removal doesn’t fix the missing libmmd.dll error, some leftover files or Registry entries might still be conflicting with Windows. So, I recommend using an effective software uninstaller to wipe all traces of the previous installation!

5. Perform a system restore

2. Click the System Restore button.
3. Select the Choose a different restore point option, if available, and click on Next.

Remember, the SFC scan and an OS reinstall won’t help you when libmmd.dll is not found in Windows because it’s a non-Microsoft DLL. So, when nothing works, it’s wise to contact the app developers.
