Hello, my processing is giving an error when generating the DSM. The message appears (Number of points retrieved by provider is different than asked.) I already tried changing the settings in the Calibration and Point Cloud steps. Here is the processing log.

I’ve also see the same message with this version. I reinstalled the latest stable version (1.43.2) and processed the DSM without issue. ---

Nope I’m getting this on 1.45.1, will try going back to 1.43.2 and see if it helps. ![Screenshot 2023-05-12 at 11.45.55 AM](https://global.discourse-cdn.com/pix4d/original/2X/1/1d02de35187bc155e58681c8440dd6651ee4fc00.png) ---

Andrew, Can you share the windows installer file with me? I went from (1.39) to (1.45.1) so i cannot download (1.43.2). I’m hoping I can open my 1.45.1 project in the 1.43.2 version\> 1.39 doesn’t let me. ---

Hi @xzamora All the installer files of the past versions can be found in [Technical release notes - PIX4Dmatic](https://support.pix4d.com/hc/en-us/articles/360044709531-Technical-release-notes-PIX4Dmatic?source=search). > I’m hoping I can open my 1.45.1 project in the 1.43.2 version\> 1.39 doesn’t let me. If you still have an issue opening the 1.45.1 project in 1.43.2, please feel free to attach the log file for us to troubleshoot further what the cause is. 🙂 You can follow this article to export the log file: [How to export log files - PIX4Dmatic](https://support.pix4d.com/hc/en-us/articles/6478094072093-How-to-export-log-files-PIX4Dmatic?source=search) Always remember to have the project folder and the dataset’s folder on a local disk/drive (typically C:/ or D:/) I hope this helps!
