Hello everyone,

It’s my first time using Slicer (latest version not nightly) and when I want to load the dicom files everytime I have this message “Could not load: 1: 3D CBCT Stitched Volume as a Scalar Volume”.

I’ve looked [here](https://discourse.slicer.org/t/hi-i-have-problems-solving-the-couldnt-not-load-scalar-volume-problem/2840) but I don’t know how to use this patch and I’m not sure it’s going to resolve the problem.

here the log file :

Probably means this issue noted in [the FAQ](https://www.slicer.org/wiki/Documentation/4.10/FAQ/DICOM) is the problem:

> - Try moving the data and the database directory to a path that includes only US English characters (ASCII) to avoid possible parsing errors. No special, international characters are allowed.
