Answer:

Helena Crossbow Herbicide is not labeled to control wintercreeper/Euonymus/spindle though the active has been used for control. That is a kind of evergreen plant, so you would likely need to cut the plant down and then immediately treat the cust with glyphosate or triclopyr to prevent regrowth.
 
Keep in mind that a product that can kill the wintercreeper can also harm your vinca minor (or other groundcovers) and the crepe myrtle. So physical removal and/or careful spot treating with a non-selective herbicide will pose much less risk to the desirable plants.
