Troubleshooting:

If the system doesn't have Internet access while [installing the .NET Core Hosting Bundle](xref:host-and-deploy/iis/index#install-the-net-core-hosting-bundle), this exception occurs when the installer is prevented from obtaining the *Microsoft Visual C++ 2015 Redistributable*. Obtain an installer from the [Microsoft Download Center](https://www.microsoft.com/download/details.aspx?id=53840). If the installer fails, the server may not receive the .NET Core runtime required to host a [framework-dependent deployment (FDD)](/dotnet/core/deploying/#framework-dependent-deployments-fdd). If hosting an FDD, confirm that the runtime is installed in **Programs & Features** or **Apps & features**. If a specific runtime is required, download the runtime from the [.NET Download Archives](https://dotnet.microsoft.com/download/archives) and install it on the system. After installing the runtime, restart the system or restart IIS by executing **net stop was /y** followed by **net start w3svc** from a command prompt.

* An FDD may have been deployed and the *Microsoft Visual C++ 2015 Redistributable (x64)* isn't installed on the system. Obtain an installer from the [Microsoft Download Center](https://www.microsoft.com/download/details.aspx?id=53840).

Install the *.NET Core Hosting Bundle* on the hosting system. The bundle installs the .NET Core Runtime, .NET Core Library, and the [ASP.NET Core Module](xref:host-and-deploy/aspnet-core-module). The module allows ASP.NET Core apps to run behind IIS. If the system doesn't have an Internet connection, obtain and install the [Microsoft Visual C++ 2015 Redistributable](https://www.microsoft.com/download/details.aspx?id=53840) before installing the .NET Core Hosting Bundle.
