Dear All,

I started work on [SlicerSegmentationRecipes/VesselSegmentationBySubtraction at master · lassoan/SlicerSegmentationRecipes · GitHub](https://github.com/lassoan/SlicerSegmentationRecipes/tree/master/VesselSegmentationBySubtraction)  
I tried to run the Elastix module, but I keep getting the same error :  
Error: Command ‘elastix’ returned non-zero exit status 4294967294.  
It occurs in both the Stable(5.0.3) and the Preview Release.  
Do you have any solution for it?

Thank You in advance,

Oliver Faris Halaseh

Dear All,

I got the same error message: “Command ‘elastix’ returned non-zero exit status 4294967294.”  
I am using Windows 10 and Slicer version 5.2.2.

This is the error message from the Python window

[FD] ERROR: the output directory "C:\Users\Palkovics Dániel\AppData\Local\Temp\Slicer\Elastix\20230420\_172652\_127\result-transform" does not exist.

subprocess.CalledProcessError: Command ‘elastix’ returned non-zero exit status 4294967294.

Is there a solution to this on Windows?

Thank you very much

Daniel

Can you check if installing Slicer in a folder that only contains ASCII characters (no accented characters such as `á`) makes any difference?  
Does registration work between `MRBrainTumor1` and `MRBrainTumor2` sample data sets?
