Failed to create folders - R0015 - PIX4Dfields
Error message
Failed to create folders, "R0015: Could not create required application folders. Interacting with projects will not be possible..."

Solution
- Make sure that the user has writing access to the selected folder.
- Make sure that the disk is not selected as the final folder. (for example,
D:\orE:\)
Create a folder inside the disk and select the latter. (for example,D:\PIX4Dfields\) - Make sure that no special characters are used on the path to the folder like middle bars.
- Ensure that the storage disk hasn't changed. Sometimes from
D:\/ toE:\or vice versa.
