Hi,

I am trying spharm in Slicer Salt on Windows 11. I directly ran the extension in Slicer. I got two mice mandibles and I filled all the internal holes for the segmentations. I followed the [tutorial](https://bit.ly/3wSrpKC) from Salt website. The raw VOLs, input VTK, and label maps as well as the output from using the label maps are in this [zip file](https://drive.google.com/file/d/1WxUGHAnY5fj-xQpFl0GQSn38-qvE_ctq/view?usp=sharing). The source volumes are 129S1\_SVIMJ and 129 X1\_XVJ from [OSF | High Resolution microCT scans of Inbred Mice](https://osf.io/xzj4t/).

I could not open the output in ShapePopulationViewer. The full log is [here](https://drive.google.com/file/d/15utNg3UTZ7CkFqardRgNDCwr8E_Qy7WG/view?usp=sharing).The error message is:

```auto
ShapePopulationViewer standard error:
Qt: Untested Windows version 6.2 detected!
libpng warning: Interlace handling should be turned on when using png_read_image

```

I wonder if it is related to how I installed ShapePopulationViewer. I could not find it in the Extension Manager, so I downloaded [v1.3.2\_windows](https://www.nitrc.org/frs/?group_id=759) and added the .exe file to Slicer Modules. However, when I tried to load any file from the spharm output either in shapePopulationViewer in Slicer or the exe file, it just reported the above error and forced closing the app.
