Download Microsoft .NET Framework 4.5.2 Offline Installer

If you are trying to run an older application or game on Windows and receiving an error message like "The program can't start because MSCVP100.dll is missing" or a prompt to install a specific framework, you likely need Microsoft .NET Framework 4.5.2.

While Windows often tries to download these components automatically via Windows Update, using the Offline Installer is the most reliable method, especially if the target computer does not have an active internet connection or if the automatic update is failing.

Here is everything you need to know about downloading and installing the .NET Framework 4.5.2 offline installer.

Q2: Is .NET Framework 4.5.2 still supported by Microsoft?

A: Mainstream support ended in 2016, and extended support ended in 2021. However, security patches for the underlying runtime are included in newer versions (4.8). You should only install 4.5.2 if you have a legacy app that refuses to run on 4.8.

Do You Really Need 4.5.2?

Before downloading, check if your software explicitly requires 4.5.2. Many apps that claim to need it will run perfectly on .NET 4.8 (the last supported 4.x version for Windows 7/8/10/11). However, some legacy applications check the exact build number and refuse to launch without 4.5.2 installed. download microsoft net framework 4.5 2 offline installer

If you are setting up an old ERP system, industrial control software, or a proprietary internal tool – keep the offline installer handy.

System Requirements

Before downloading, ensure your machine meets these requirements:

Note: .NET Framework 4.5.2 is not officially supported on Windows 11 or later versions of Windows 10 that come with .NET 4.8 pre-installed. However, you can still enable it via "Windows Features" if software demands it. Download Microsoft

⚠️ Important: Official Download Source

Only download the installer from Microsoft’s official website. Third-party sites may bundle malware or outdated versions.

Official Microsoft Download Center URL:
https://www.microsoft.com/en-us/download/details.aspx?id=42642

On that page, look for the file named:
NDP452-KB2901907-x86-x64-AllOS-ENU.exe

Note: Microsoft has largely replaced the 4.5.2 download page with a redirect to .NET 4.8. However, the direct standalone package is still available via the official Microsoft Update Catalog or Volume Licensing Service Center.

Q1: Can I install .NET 4.5.2 alongside .NET 4.8?

A: Yes. Higher versions (4.6, 4.7, 4.8) are in-place updates to 4.5. “In-place” means they replace 4.5.x. If you install 4.8, you cannot “downgrade” to 4.5.2 without uninstalling 4.8. However, most apps that require 4.5.2 work on 4.8 because they are backward-compatible. On that page

Title: Download Microsoft .NET Framework 4.5.2 Offline Installer: A Complete Guide

If you manage multiple computers, work in an environment with limited internet connectivity, or simply prefer keeping installation files for future use, the offline installer (also known as the standalone package) for Microsoft .NET Framework 4.5.2 is an essential tool.

Many developers and IT administrators still require this specific version for legacy applications that are incompatible with newer .NET runtimes (like 4.6, 4.7, or 4.8). Here’s what you need to know to get the correct, safe offline installer.

2. PowerShell Feature (Automation)

If you intended to "put together a feature" to handle this installation programmatically (for example, in a setup script or deployment pipeline), here is a PowerShell function that downloads the installer and runs it silently.

    .SYNOPSIS
    Downloads and installs .NET Framework 4.5.2 silently.
