There is no installation file other than the driver that is installed in the QuartusII directory,
Example Directory,
C:\altera\quartus50\drivers\usb-blaster If you are using Windows, windows should detect the presents of a new USB device, if it does then you
must follow the instructions that are in the above link to the user guide for installation. If windows does
not detect a new device, then you may have something wrong with you USB port or Windows drivers to your
USB port.
Good Luck,
