Pix4D Desktop shuts down when the Quality Report is displayed


Pix4D Desktop is crashing when the quality report is displayed in the User Interface.



The quality report is displayed automatically after each step of processing unless the related option is unselected.

The software is crashing after each processing step is completed when the quality report is displayed automatically in the user interface. 



The cause of this issue is a library called LavasoftTcpService64.dll. 



To solve the issue, remove the LavasoftTcpService64.dll library. To do so, search for the application Webcompanion from Lavasoft in the Control Panel and uninstall it.

If this software does not exist in the installed software, follow the steps below:

1. In the Windows Search, type cmd to find the Command Prompt.
2. Right-click on the Command Prompt and select Run as administrator.
3. Enter the following command to reset the network adapter:netsh winsock reset.
4. Restart the machine.
5. Delete these two files:
6. Try to open the quality report in Pix4D Desktop again.

    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,

    Hi, I have the same issue as Giljae, the quality report makes shut down the program, I already tried lower resources level of my computer, and there's no change, my computer specs are:

    Intel core i9 9900x

    Ram 128g

    SSD 1 tb

    GPU Nvidia quadro p4000

    I'm processing a 7000 image dataset, the processes were made properly, but I had to do it one by one because at the en of every process, a quality report is generated, but it always shutted down, so, I have the processed project, but not the report, Maybe it could not represent any problem if the following steps did not depend on the generation of it, but it  actually does. 

    That means that if I have a 7000 image dataset, I will need to be there all the time just waiting for the program shuts down to run the next steps.

    Do you have any solution for this?

  • Marco (Pix4D)

    Hi Roberto,

    Which Pix4Dmapper version are using?
    There is a known bug during Quality Report generation for versions prior to 4.5.2.

    If you have an older version, I recommend you to upgrade. This should impede the software to crash.

    Hope this will help.

  • Roberto Velasco

    I'm using 4.4.12 but it only happens with the 7000 image dataset, with other datasets with less images is ok

  • Marco (Pix4D)

    Hi Roberto,

    At this stage I cannot tell you what is going on.
    Could you please upload your quality report and *.log file here so we can investigate?


  • Roberto Velasco

    I have uploaded the log file, I don't have the quality report



  • Marco (Pix4D)

    Hi Roberto,

    Have you tried to upgrade to the version 4.5.2 to see if it does manage to complete the processing?
    Because I have looked at your *.log file and the only thing I can propose to you at the moment is the workaround described in this post where you have already replied.

    Which resolution value are you setting up for the step 3?


  • Thomas Pingel

    I had this issue (version 4.4.12) with a brand new laptop and Pix4D install, and was able to resolve it by making sure Pix4D was using my nvidia graphics card by default, not in the Pix4D processing settings, but in the NVidia control panel.  I made sure to set the "Manage 3D Settings" to use the nvidia processor in both the Global Settings and in the Program Settings for pix4dmapper.exe specifically.
