Is there an anwswer in this link? All I find are problems related to Dell computers, which do not apply to my problem, or to contact tech support...

[Walter Roberson]

That link is all the publicly known information about the problem. If none of those solve the problem, then you will need to either contact technical support or do without.

In some cases you might need to regenerate prefdir

Hi Fernando,

The error is suggesting that there is some trouble loading the DLL file. As you have not attached the code files and other details, here are some general steps to check:

• Check File Existence: Verify that the file “mldrivebuiltins.dll” exists in the specified directory: “C:\Program Files\matlab\R2017a\bin\win64\.”
• Permissions: You might need administrative privileges so check if you have the necessary permission to the MATLAB installation directories.
• Corrupted file: Try reinstalling MATLAB as the DLL file might be corrupted and the installation might not have happened properly
• Environment variables: Ensure that your system's environment variables, particularly PATH, include the correct paths to MATLAB's binaries.
• Firewall: Sometimes, antivirus software or firewalls can block or interfere with program files. Temporarily disable them to see if the issue persists.

Lastly, update MATLAB to a newer version if anything above doesn’t work.

Hope this helps!
