I have and Arducam USB adapter - UC931 - Rev D connected to a MT9J003. I got the drivers installed properly and the camera is being detected. I am using Windows 10. However when I launch the GUI program, the option to load a config file is greyed out. Did anyone else have this issue, if so how did you solve it ?

Please let me know. Thanks in advance.

Please help me so that I can load a config file

I went about a different route, I clicked on “File > Open” on the top left corner of the GUI and went to the config directory to select the camera configration file. Hope that helps
