Some advice: you may want to re-consider this approach, even though it may feel like you risk being ripped off, your reputation and overall sentiment about your product are probably worth more than the 59$ you don't want to give back. If someone feels they can't use your product - for any reason - it's going to feel unfair to them that they can't get a refund, no matter who's fault it is. Note that the top reply to your thread is a dissatisfied ex-customer who felt obliged to post about his bad experience (fair or otherwise), and I bet that may have almost immediately cost you a few sales. I'm not saying give everyone a refund who asks for one, but just saying "it's not a SaaS product and I can't turn it off" might not be the best rationale (and certainly won't impress any customers who are legitimately unable to use your product). I would err on the side of trusting your customers, and accept that some might rip you off but most won't, and you'll partially salvage a bad product experience with some good customer service.
