I downloaded and installed slicer 4.11 in my Applications folder.
Slicer starts normally but I can’t load volumes (.nii) or load dcm files. After starting, the following warnings appear.
When loading module “DICOM” , the dependency “SubjectHierarchy” failed to be loaded.
When loading module “DICOM” , the dependency “SubjectHierarchy” failed to be loaded.
When loading module “DICOMPatcher” , the dependency “DICOM” failed to be loaded.
When loading module “MarkupsWidgetsSelfTest” , the dependency “Markups” failed to be loaded.
When loading module “MultiVolumeImporter” , the dependency “MultiVolumeExplorer” failed to be loaded.
When loading module “NeurosurgicalPlanningTutorialMarkupsSelfTest” , the dependency “Segmentations” failed to be loaded.
When loading module “PlotsSelfTest” , the dependency “Plots” failed to be loaded.
When loading module “SegmentEditor” , the dependency “Segmentations” failed to be loaded.
When loading module “SegmentStatistics” , the dependency “SubjectHierarchy” failed to be loaded.
When loading module “SubjectHierarchyCorePluginsSelfTest” , the dependency “SubjectHierarchy” failed to be loaded.
When loading module “SubjectHierarchyGenericSelfTest” , the dependency “SubjectHierarchy” failed to be loaded.
When loading module “TablesSelfTest” , the dependency “Tables” failed to be loaded.
I read the warning, “You cannot install extensions into the read-only volume so you must copy before installing extensions”. I was unsure if that meant I had to load extensions separately, and how to do that.
Thanks for any help!

Are you using latest stable version (Slicer-4.11.20200930)?

Yes - 4.11.20200930. I tried the preview release as well but had similar errors.

Could you upload the application log (menu: Help/Report a bug) somewhere (dropbox/onedrive/gdrive/…) and post the link here? Thanks.

Andras - Thanks for your help. The log file is pretty short so I hope you don’t mind that I post it here (below).

Could you please try deleting Slicer completely, then reinstalling it, without installing any extensions?

Hi Andras. Your comment made me realize that the .ini files weren’t deleted with the new install. Once I deleted them, it solved the problem. Thanks for your help!
