Hi @Nardine Nassif,

The error that you are seeing typically occurs when MATLAB cannot load one or more native libraries due to missing system dependencies—most commonly, required Visual C++ runtime libraries.

Here are a few steps that can help resolve the issue:

1. Install Visual C++ Redistributables (Both x64 and x86)

Even if you are on a 64-bit system, you will need both versions:

Microsoft Visual C++ Redistributable for Visual Studio, be sure to install both:

• vc_redist.x64.exe
• vc_redist.x86.exe

After installation, restart your machine and try launching MATLAB again.

2. Check Your PATH Environment Variable

Make sure MATLAB's binary path is included in your system's PATH:

C:\Program Files\MATLAB\R2018b\bin\win64

Verify this by running in MATLAB:

getenv('PATH') 

If it is missing, add it by going to System Properties then to Environment Variables.

3. Run MATLAB as Administrator

Sometimes, access issues prevent DLLs from loading properly. Try right clicking the MATLAB shortcut and selecting "Run as administrator."

This should help fix the issue.
