arcpy near analysis fails

TinaOosterom1

When I run >>>arcpy.Near_analysis("ACN_Select","Derden","150 Meters", "NO_LOCATION", "NO_ANGLE","PLANAR") in the python window in ArcMap 10.4, it returns the correct numbers in the field NEAR_DIST.

However, if I run the same in PyScripter:

import arcpy
arcpy.env.workspace = "C:\\Geoplay\\GLO\\Output.mdb"
arcpy.env.overwriteOutput = True

if arcpy.CheckExtension("Spatial") == "Available":
    arcpy.AddMessage("Checking out Spatial")
    arcpy.CheckOutExtension("Spatial")
else:
    arcpy.AddError("Unable to get spatial analyst extension")
    arcpy.AddMessage(arcpy.GetMessages(0))
    sys.exit(0)

ACN_Select = "C:\\Geoplay\\GLO\\GLO.gdb\\ACN_Select"
Derden = "C:\\Geoplay\\GLO\\GLO.gdb\\Derden"

#Near Analysis
arcpy.Near_analysis(ACN_Select,Derden,"150 Meters","NO_LOCATION","NO_ANGLE","PLANAR")
