If you purchased an MC-III with the NuFlo USB Adapter option, the USB driver must be installed to enable USB connections.
MC-III users who are not using the USB Adapter only need to install the MC-III software.
Note: Internet Explorer is required to install MC-III from this screen.
To use a different browser, start Windows Explorer, browse the CD drive (or where setup files were unzipped), open the install folder, and double-click on mc3exp_setup.exe.
