    "Html": "\r\n<p>I had typed in a long detailed answer for your question, but my internet connection went down, and I lost it.</p>\r\n<p>An SFX is a .NET application. As such it requires that the .NET Framework be present on the computer that runs the SFX.&nbsp; There is no way for a .NET application itself to guarantee that the requisite .NET Framework is available before running.</p>\r\n<p>One approach to insuring that pre-requisites in general are available on a computer is to package the application into an MSI (Microsoft Installer).&nbsp; You can build one of these using a Setup and Deployment project in Visual Studio.&nbsp; In the project\r\n you can stipulate the pre-requisites, including the .NET Framework runtime. An MSI offers other features as well:&nbsp; the user can choose an installation directory, can review and select optional features for the application, and can uninstall the application\r\n later using MSI.&nbsp; This is probably the best way to distribute a custom .NET application that is beyond simplistic.</p>\r\n<p>The MSI is not a good approach to distribute an SFX application.&nbsp; I said earlier that an SFX is just a .NET application.&nbsp; So why should the SFX be treated differently than&nbsp;other .NET Applications? It's this: the SFX is not intended to be run\r\n repeatedly, and used over the long term. It's typically something you run once.&nbsp; As such, a better way to insure pre-requisites in this case is to tell the user to install the .NET Framework, perhaps by referring the user to a URL where the .NET Framework\r\n can be downloaded, like <a href=\"http://www.microsoft.com/net/download.aspx\">http://www.microsoft.com/net/download.aspx</a>&nbsp;.</p>\r\n<p>A similar approach may be appropriate for deploying your application. If it's a fairly simple app, then just asking people to install .NET 4 with a URL click, might be the right approach.</p>\r\n",
