The installation process for MATLAB crashes silently during the post-installation steps on Windows 10 Builds 1809 and later. This results in an incomplete installation of MATLAB products. Some of the symptoms of this incomplete installation include the following:
  • MATLAB did not go through an activation process, instead requiring you to go through activation when first starting up MATLAB.
  • MATLAB uninstaller is not registered, and MATLAB is not found under the list of applications that could be uninstalled via Windows Settings utility (Windows Settings -> Apps -> Apps & features).
  • Some of the MATLAB and Simulink file types (e.g., MATLAB file, MAT-file, Simulink Model file) might not be properly associated with appropriate MathWorks products.
If you are unsure of what version of Windows you are using you can run the following command in a Windows command prompt.

Workaround for R2015a
To work around this issue for R2015a, use the following steps: # Please note that this .dll will ONLY work for R2015a. Download the dll attached to this article. # Navigate to \bin\win64\libmwwinreg.dll in your MATLAB installation files. These installation files are the ones used for offline installation. Please refer to the article below for more information.
How can I get MATLAB installation files for use on an offline machine?
  1. Replace the file existing libmwwinreg.dll file with the new file and run the installer.

Workaround 1
To work around this issue, use the following steps:

  2. Re-install the same version of MATLAB. The installer will run to completion.
  3. Confirm that the installation was successful by finding MATLAB listed under the list of applications that could be uninstalled via the Windows Settings utility.
