If you can't see your USB-Blaster in the programmer window then the next place to look is in the control panel Device Manager (it appears in different places in different versions of windows).

If the USB-Blaster shows up there as a USB-Blaster then you almost certainly have a problem with your Quartus install, please don't reprogram the EEPROM.

Reprogramming the EEPROM will only help if your cable somehow shows up as a FTDI USB<->Serial device. In other cases reprogramming your EEPROM probably won't help and it could well make things worse.
