Before wasting time going the SWP route, LKH should probably do a board search and read the various posts about it. When I tried it, it was pretty crappy software, crashed a lot, and little or no support.
LKH - on boards like this, it's a good idea to always be cautious of any recommendations from anyone who has posted nothing but messages about that same product and taking the opportunity each time to post the URL to the product's website. The poster could very well be legit, but you never know. A little search and checking out to see what others have posted about a product could save you a lot of wasted time.
