Troubleshooting an Installation That Uses Dongles

If your MATLAB installation requires the use of dongles, it can potentially run into conflicts with other applications you may be running that also use dongles. A dongle is a hardware-based security device that attaches to the USB port of a computer.

To use a dongle, MATLAB requires a specific set of dongle drivers. If you remove other applications from your computer, these applications may delete the MATLAB dongle drivers as well as their own.

To help troubleshoot problems with dongles, MATLAB includes a utility program called dongleutil.exe. The dongle utility program can be used to

• Determine the version of the currently installed dongle drivers. The MathWorks Technical Support might request this information if you call.
• Specify the minimum version of the dongle drivers required by MATLAB.
• Install the dongle drivers required by MATLAB.

If an installation uses dongles, the installer includes the dongleutil.exe utility in the $MATLAB\bin\win32 folder, where $MATLAB represents your MATLAB installation folder.
