Running some initial processing in Discovery on my laptop, whilst I try and process in full Mapper on a PC   It was working last week - I upgraded, as requested, and now it crashes when I try and load a file. I can sometimes open a project from the front page (it crashes if I pick from an Explorer list), but not always.   Rolled back to previous version. Now does the same thing.   All very frustrating! ---

Dear Paul, This issue has already been solved in a personal support request. To help other followers of the post facing the same issue, we will summarize our answer here:  Based on the error message of the event viewer (Faulting module name: ntdll.dll), the crashes do not seem to be related to Pix4Dmapper; it seems to be related to a faulty hardware component, a driver or an issue of the operating system. Since you have already run a hardware check and updated the drivers, this seems more related to the operating system. You can keep this in mind if you face this issue in the future. Best regards, ---

Found this while looking for a solution! File Explorer Interaction shuts down Pix4D Desktop on Dell Machines Updated: March 06, 2017 15:40 [Follow](https://support.pix4d.com/hc/en-us/articles/115001141506-File-Explorer-Interaction-shuts-down-Pix4D-Desktop-on-Dell-Machines/subscription) **Error** Pix4D Desktop, version 3.1 or later, is crashing when interacting with the File Explorer in Dell machines.    **Description** Pix4D Desktop is crashing during any interaction with the File Explorer. For example, when: - opening a project from the \_Project \_menu. - saving as the project. - importing a GCP file. - selecting the images when creating a project, etc.   **Cause** The crash is caused by a library which is part of a software called Dell Backup and Recovery (or AlienRespawn, alternatively).There is a conflict between a later version of a library used in Pix4D Desktop and an earlier version used in Dell Backup and Recovery that is causing the crash.   **Solution** Remove the Dell Backup and Recovery software (or AlienRespawn, alternatively) from the computer and try to create a project again.   It solved the problem!! ---

Ole, that’s really interesting.   My laptop (the machine that gave me issues) is a Dell. However, so is my desktop work PC, which is fine. Just looked, and it does not have the Backup and Recovery software on it. This seems to prove your point.   Unclear as to why Pix would update software so it no longer works - remember this only happened at upgrade time - but what can you do?   I’ll go to my laptop and delete - it isn’t as if I used the facility anyway.   Cheers! ---
