Don't buy this product. I purchased the latest version of ShellMegaPack (5.0) for .NET. The installations don't work - the assemblies to not get registered or even installed. Repeated emails to tech support and sales support have gone unanswered. The web-based incindent report forms do not work and there are no contact phone numbers provided. If you're like me and don't have 200 bucks to throw away then stay away from this product.
