I am trying to convert a raster to polygon in ArcGIS 10.2.2 but when I run the tool, it says complete but no polygon file is created and the tool window pops up again. I have tried converting the raster to integer type, but still no luck! I am using a raster projected from Mollweide projection to GCS WGS 1984 and both the input raster and output location is in a geodatabase.
I know this question is old, but if anyone else runs into this - I had the same issue and my problem was that I was trying to save the polygon with the same name as the raster in the same geodatabase. I changed the name of the output polygon and the issue was resolved.
