64 bit asp net mvc app wont run


ASP.NET is a popular programming language used for developing web applications. However, sometimes developers may encounter issues while running ASP.NET MVC app, especially on a 64-bit system. In this article, we will explore some possible solutions to this problem.

Check System

Before diving into troubleshooting, it is essential to ensure that your system meets the necessary requirements for running ASP.NET MVC apps. Make sure you have a 64-bit operating system installed, along with the required versions of .NET and Visual Studio.

Verify Application Configuration

Next, double-check the configuration settings of your ASP.NET MVC app. Open the web.config file and ensure that the target framework is set to the version. Additionally, verify that the application pool in IIS is configured correctly for running 64-bit applications.


One common reason for an ASP.NET MVC app not running on a 64-bit system is missing or incompatible dependencies. Ensure that all the required libraries and packages are properly referenced and compatible with the 64-bit architecture. You can use NuGet package manager to manage and update dependencies easily.

Enable 32-bit Applications

In some cases, enabling the option to run 32-bit applications on a 64-bit system can resolve compatibility issues. To do this, open IIS Manager, select the application pool used by your ASP.NET MVC app, and set the “Enable 32-Bit Applications” option to true.

Check Application Logs

If the above steps do not resolve the , it is crucial to check the application logs for any error messages or exceptions. These logs can provide valuable insights into the root cause of the problem. Analyze the logs and address any specific errors or exceptions accordingly.


using System;

namespace MyApp
        public static void Main(string[] args)
            Console.WriteLine(", ASP.NET!");

In the above example, we have a simple ASP.NET MVC app that prints “Hello, ASP.NET!” to the console. Ensure that the code is properly compiled and all necessary dependencies are included. If the app still doesn't run, the troubleshooting steps mentioned earlier to identify and resolve the issue.


Running an ASP.NET MVC app on a 64-bit system may encounter certain challenges, but with the right approach, these issues can be resolved. By checking system requirements, verifying application configuration, managing dependencies, enabling 32-bit applications, and analyzing application logs, developers can overcome the hurdles and ensure their ASP.NET MVC apps run smoothly on 64-bit systems.
