Error message

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

Solution 

1. Make sure that the user has writing access to the selected folder.
2. Make sure that the disk is not selected as the final folder. Create a folder inside the disk and select the latter.
3. Make sure that no special characters are used on the path to the folder like middle bars.
