Hello, this is Emily.
Depends on what kind of camera you have, go to your camera's local menu, look for file transfer mode. Make sure it is set to PTP (Picture Transfer Protocol). I wouldn't be able to tell you exactly where it is in the Camera settings because every brand/model can be different. Refer to your camera's manual if you have trouble finding it.
A workaround solution is to take the memory card out of the digital camera, usually it is an SD card. If your computer has an SD card reader, you can insert it directly there and read it from File exporer. I am a photographer myself. I always export my photos this way because then I don't need to rely on my camera's settings and keeping up with the camera driver.
