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 ofthe 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 matlabroot \R2006b\ bin \Win32 folder, where matlabroot
represents your MATLAB installation folder.
