Visual C++ Redistributable Requirement

On older versions of Windows, such as Windows Server 2012 R2, it is crucial to install the Visual Studio C++ Redistributable to avoid encountering confusing error messages in the Windows Event Log. These error messages may indicate that the data is the error, which can be perplexing and hinder troubleshooting efforts. To resolve this issue, it is necessary to install the appropriate version of the Visual C++ Redistributable.

Installing the Visual C++ Redistributable ensures that the required runtime components are available for your applications to function properly. This redistributable package includes the necessary DLL files and libraries that are essential for executing programs that are written using Visual C++.

By installing the Visual C++ Redistributable, you can avoid compatibility issues caused by missing dependencies and ensure that your applications run smoothly on your Windows Server.

To install the Visual C++ Redistributable, follow these steps:

Visit the official Microsoft website or search for “Visual C++ Redistributable” in your preferred search engine.
Choose the appropriate version of the redistributable based on your operating system and architecture (32-bit or 64-bit).
Download the installer file and run it.
Follow the installation wizard’s prompts to complete the installation.
Once the installation is finished, restart your system to ensure that the changes take effect.

If you encounter any issues during the installation process or have any questions, refer to the official Microsoft documentation or seek assistance from the Microsoft support community.

By installing the Visual C++ Redistributable, you can avoid the error messages related to missing dependencies and enhance the stability and performance of your applications on older versions of Windows.

Options

When installing .NET Core, there are several options available that allow you to customize the installation process to suit your specific needs.

Customizing the Installation

By running the installer from an administrator command shell, you gain access to various options. These options enable you to skip the installation of certain components, such as the ASP.NET Core Module or the .NET Core runtime, if they are not necessary for your hosting requirements.

When considering these options, it is essential to carefully assess their implications before proceeding with the installation. Selecting the relevant components ensures an efficient and tailored installation process.

Skipping the ASP.NET Core Module

If you do not require the ASP.NET Core Module for your hosting setup, you can choose to skip its installation. This can be beneficial if you are using a different web server or if you have specific requirements that do not rely on the ASP.NET Core Module.

Opting Out of the .NET Core Runtime

In certain scenarios, you may not need the .NET Core runtime installed on your system. For example, if you are only deploying pre-compiled applications that already contain the necessary runtime, you can choose to exclude it from the installation process.

Considering Your Hosting Requirements

When deciding which components to install and which to skip, it is crucial to consider your specific hosting requirements. By customizing the installation to match your needs, you can optimize the performance and functionality of your .NET Core applications.

Component	Description
ASP.NET Core Module	The ASP.NET Core Module enables ASP.NET Core apps to run with IIS. If you choose to install this component, make sure it aligns with your hosting environment and requirements.
.NET Core Runtime	The .NET Core runtime provides the necessary libraries and components for running .NET Core applications. Evaluate whether you need this runtime installed or if your applications already have the required runtime bundled.

Restart IIS

After installing the .NET Core Hosting Bundle, it is essential to restart IIS manually to ensure that the changes take effect. This step is particularly important if you encounter any issues with the dotnet CLI tooling or if the tooling is not available on the PATH for running IIS worker processes.

To manually restart IIS, follow these steps:

Open a command prompt as an administrator.
Type the command net stop was /y and press Enter. This command stops the Windows Process Activation Service (WAS).
Wait for the service to stop completely.
Type the command net start w3svc and press Enter. This command restarts the World Wide Web Publishing Service (W3SVC) and any dependent services.
Wait for the service to start successfully.

Restarting IIS ensures that the .NET Core Hosting Bundle is properly integrated and allows IIS worker processes to access the necessary components for running ASP.NET Core apps smoothly.

By following these steps, you can ensure that your IIS server is ready to host and run your ASP.NET Core applications.

Module Version and Hosting Bundle Installer Logs

If you need to determine the version of the ASP.NET Core Module installed on your hosting system, follow these steps:

Navigate to the %PROGRAMFILES%\IIS\Asp.Net Core Module\V2 directory.
Locate the aspnetcorev2.dll file.
Right-click on the file and select Properties.
In the Properties window, go to the Details tab.
Look for the File version and Product version, which represent the installed version of the module.

This information can help you troubleshoot any compatibility issues or check if you have the latest version of the ASP.NET Core Module installed.

Hosting Bundle Installer Logs
