Hi  
I’m new in Slicer. I’ve installed Slicer 4.10.2 for Windows 8.

While trying to use Surface Cut, I can see that Fiducial Placement doesn’t work. My button appears as it’s inactive (grey) and I can’t click on it.

I’ve already installed “SegmentEditorExtraEffects” extensión, including “Marks Up To Model”, then I re-started slicer, but it sill doesn´t work.

The extension was installed in the folder: AppData

Error:

Cannot load library C:\Users\whoareyou\AppData\Roaming\NA-MIC\Extensions-28257\MarkupsToModel\lib\Slicer-4.10\qt-loadable-modules\qSlicerMarkupsToModelModule.dll: No se puede encontrar el m?dulo especificado.

Sorry, when we updated the extension for Slicer-4.11, something went wrong. Until we fix it, you can use Slicer-4.11.
