Why do I receive a java.io.IOException error when installing MATLAB on an offline machine?

When installing MATLAB on an offline machine using ISO files, I run into an error message at 99% of the installation process:

ERROR: Error: background merge hit exception: _0(4.6):C69875 _1(4.6):C44803 _3(4.6):C29519 _4(4.6):C15713 _a(4.6):C16787 _7(4.6):C8796 _6(4.6):C7345 _9(4.6):C12472 _8(4.6):C5991 _2(4.6):C6043 _5(4.6):C1820 into _b [maxNumSegments=1]

This error is due to corrupted installation files. You will have to uninstall your corrupted installation and install it again downloading new ISO files.

The workflow below outlines the steps to perform to resolve this error:

1. Perform a clean uninstallation

Steps to perform a clean uninstallation vary depending on your operating system, follow the steps provided on the articles below:

• Windows System: How do I perform a clean installation of MATLAB on a Windows system?

3. Get the ISO files prepared for the installation

Once your ISO files are downloaded, you will have to perform the following actions before launching the installer:

• If using a shared network location or USB drive for your installer, merge your ISOs: How can I obtain a single installation package for MATLAB with the ISOs (Merge the ISO Images)?
• If burning DVDs: How do I install MathWorks products using an ISO image?

4. Launch the installer

Mount the DVD/USB drive or access your shared network location and launch setup.exe located in the main directory.

Perform your installation as desired.
