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\32Bit\
winusb\x86\MCHPWinUSBDevice.inf
or
C:\Program Files
(x86)\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.
