easiest way I have found to do this safely by myself is to take a smooth rope and climb your stand, tie it off to the frame of the seat itself. After that wrap the rope around the tree once and let it hang to the ground. Climb down and remove your ladder bracing and straps. pick the rope up and hold it firmly and give the stand a pull or push to move it away from the tree to where it's got pressure on the rope. then from behind the tree out of the way ease it down by the rope.
The types of stands I have used work out great using this method so hope it may give you a bit of help.
