If you don't already have it, you can get LTspice for free at:
Once you download the program, copy the circuit list and save it to a file with a .asc extension, then left-click on the file.
LTspice should find the file, load it, and display the schematic.
If it doesn't, then launch LTspice, navigate to the saved file and click on it.
Once the schematic is displayed you can edit it in any way you wish, and if you want to run it right-click anywhere on the background of the schematic and left-click on RUN when the menu pops up.
