Software freezes at 'Select Output Coordinate System"

Before describing the problem I’ll provide the general system specs of the office computer:

    • CPU: Xeon W-2175 2.50 GHz
    • RAM: 64 GB
    • GPU: NVIDIA Quadro P5000

The problem we are encountering is that every time we get to the ‘Select Output Coordinate System’ and hit ‘Next’ the software locks or freezes at that moment and doesn’t allow us to go to the next window which is ‘Processing Options Template’.

Sometimes if we wait and keep clicking Next we get to the Map View directly but the screen is all grey (where the map appears). No map either ‘satellites’ or ‘maps’ doesn’t load. The software even allows processing the jobs but after running the first 2 steps it doesn’t display anything, not even the generated point cloud. We have tried this in the following versions: 4.3.31, 4.2.27 and 4.3.24.

We have noticed on another computer that during the part where we click Next at the ‘Select Output Coordinate System’ the software stops for a moment (probably 5 secs) and then sends us to the ‘Processing Options Template’ where we can continue to work normally. If we could figure out what the software does during this moment of waiting before the ‘Processing Options Template’, we might figure out how to fix this issue on the newest computer which is causing us problems (and delays!). Thank you.


Just very recently one of our users had a similar problem - Pix4Dmapper was hanging at Select Output Coordinate System.

It turned out that when you don’t properly uninstall the software - you forget to delete some system files, the problem occurs. 

After deleting those files, and reinstalling Pix4D, the errors went away :) 

Can you give it a try by following our instruction how to completely uninstall Pix4D Desktop.

Let me know how it goes.


We did all the steps to uninstall the software but the problem persisted.

Hi Blake,

During those 5 seconds the software checks if there are some calibration targets in the datasets. It is expected no to have them in RGB dataset.

There’s a high possibility that the machine itself is causing the problems. Will be possible for you to send us the machine specs of this specific computer? I can compare it with another case trying to find some similarities and answers to our questions.

You can find this file by following this instruction: 

  1. Click the Windows Start icon and type System Information. Select the application in the list above.
  2. In the application, click File > Save… and export the content.
  3. Attach the file your_file.nfo to the reply.

You can also submit a ticket to Pix4D Support if you don’t want to post the file here.

Thank you in advance!

Thanks. I have attached the file. The computer also has some security softwares installed but we are not sure if they do come in conflict with Pix4D.

How do I attach the file? It only allows me to paste a link.

Hi Blake,

Can you use one of the sharing platforms such as Wetransferor Google Drive? 
Our team is working on the sharing-files feature that could be available here on the community but as for now, we need to use other tools :wink:


Hi Beata,
I can use Wetransfer. Do you have an email address I can send it to?

Hi Blake,

Please click on the three dots and choose the link option.
Thank you!
