Whats the use and how can i download this toolbar?
if you have an advanced license Feature Vertices To Points—Help | ArcGIS for Desktop
if not, the new scripts website is here... ArcGIS Code Sharing and if the script has been moved, it will be there, otherwise, the exact script name and author and/or URL is needed to see if it can be extracted from the old scripts archive
For what it's worth, you can make your own script that converts polyline vertices to points as simple as:
in_fc = "my_layer" # change this to a layer name
out_fc = r"C:\junk\out_fc.shp" # change this to an output location
np_arr = arcpy.da.FeatureClassToNumPyArray(in_fc,'*',explode_to_points=True) # leave alone
arcpy.da.NumPyArrayToFeatureClass(np_arr, out_fc, 'Shape') # leave alone
