3.3.3.4 If You Need to Manually Switch the Drivers

If you need to switch or associate the USB device drivers manually:

1. Open the Device Manager (under Control Panel). Look under Microchip Tools for your tool or, if you cannot find it there, under Other Devices for Unknown Device.
2. Right click on your tool name or Unknown Device and select Update Driver Software.
3. In the Update Driver Software dialog, select Browse my computer for driver software.
   Note: DO NOT select Search automatically for updated driver software. This will associate a Windows default driver with your tool, which will probably not work. If you accidentally select this, back out or exit and repeat these steps to switch to the correct driver.
4. Locate the correct device driver for your system.

   For MPLAB X IDE, the default locations for the device drivers are:

   C:\Program Files\Microchip\MPLABX\vx.xx\Switcher\64Bit\
winusb\amd64\MCHPWinUSBDevice.inf

   where vx.xx is the version number of MPLAB X IDE.

5. If a Windows Security dialog pops up, select Install this driver software anyway to proceed to switch to the selected drivers.
