I execute the program and nothing happens. I check the Task Manager and the program isn’t running. I’ve uninstalled and reinstalled it. I’m running Windows 10. First time I’ve seen this issue. ---

Hi @jhiggins1, Welcome to the Pix4D Community! I see that you also opened a direct support ticket; I replied directly there, asking for the _Events log_. I will update this thread once a solution is found. Thank you for understanding. Cheers ---

Daniele, Thanks for the quick reply yesterday. Yesterday afternoon IT came and moved me into a new laptop. I’ll install Pix4D today and see if I have the same (or new and different) issues.

I’m having an issue downloading 4.8.0 to my work computer. Once application is installed, upon opening I’m getting a message “File corrupted! This program has been manipulated and maybe it’s infected by a Virus or cracked. This file won’t work anymore.” I’ve tried repairing, uninstalling and re-installing, and even tried installing 4.7.5 and am getting the same error message. ---

Please check that the files below do not exist:** 1. On the path where Pix4D desktop (Pix4Dmapper) is installed: C:\Program Files\Pix4Dmapper make sure this folder does not exist anymore. If it exists, DELETE this Pix4Dmapper folder. 2. On the following path: **C:\Users\Your\_USERNAME\AppData\Local\pix4d** make sure this folder does not exist anymore. If it exists, DELETE this Pix4Dmapper folder. 3. C:\Users\YOUR\_USERNAME\Documents\pix4dmapper make sure this folder does not exist anymore.
