Working on my first project and I am getting a processing error.  80 images collected with a Phantom 4 (latest firmware). When I go to process in Pix4dmapper it won’t process.(ver 2.1.53 64bit). the images are of farm fields, forest, few buildings. The log file says it can’t write to the C drive and then says “no error” Any ideas - log below   [UI]: New Project clicked.

Hi @vinkienz Welcome to Pix4D Community! We need the information to be able to help you with this issue. - Can you please describe us the steps you followed before you get this warning? - Did you manage to open the project or did it fail? - Could you please send us a screenshot the moment the error occurs? - Could you please access the 1\_initial folder? Are all the files properly generated? We suspect that there might be a problem with the memory allocation. Please could you give us more information about the hardware of your notebook? - How much RAM memory: - What is the GPU: - What is the CPU: - Available hard disk space: Could you also send us the full log file (.txt file) that you will find in the results folder, as you can see in the screenshot below: ​ ![](https://global.discourse-cdn.com/pix4d/original/2X/f/ffdf449be5dc327ea57f17062e5cd9fb16706841.png) Have a very nice day!
