    Hi Giljae,

    Is your computer a 32-bit version?

    Have you been able to process first step?


  • Giljae AHN

    Sorry for the late reply.


    It's 64bit windows 10(pro) with brand new surface book 2 15in model.

    pix4d 3.1.23 version


    It happens right after the 1st step. with trying to show up a quality report.

    and the application stopped responding(crash) 

    I tried more than 5 times with same pix4d demo project

    and only one case able to finish the first step. (also crashed, I checked this by explorer, not by the application)


    Thank you.

    Hi Giljae,

    At the moment I cannot tell you what is going on.

    I can recommend you to reduce by one or two levels the use of the resources. That could impede the software to crash.

    How many image are you trying to process and what is the resolution?

    Hope this will help,
