Go to Control Panel > Programs and Features > Turn Windows features on or off . Look for .NET Framework 4.5.2 (or .NET Framework 4.5 with later updates). Frequently Asked Questions (FAQ) 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. 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. Q3: Why is the offline installer only 66 MB but installation requires 2 GB? A: The 66 MB is a compressed, bootstrapping executable. During installation, it expands into thousands of temporary files, runtime libraries, and assemblies—hence the larger disk footprint. Q4: My antivirus flagged the offline installer. What should I do? A: Some aggressive AVs flag the .NET installer as “Potentially Unwanted” because it registers deep system components. This is a false positive. Always verify the digital signature: right-click the file > Properties > Digital Signatures – ensure it is signed by Microsoft Corporation . Q5: Can I slipstream .NET 4.5.2 into a Windows installation image? A: Yes, you can add it to a Windows 7/8 image using DISM: dism /image:C:\mount /add-package /packagepath:NDP452-KB2901907-x86-x64-AllOS-ENU.exe Conclusion: Don’t Risk Third-Party Sites The Microsoft .NET Framework 4.5.2 offline installer remains a critical tool for IT professionals and developers managing legacy software. Keep a copy on your network share or external drive—you never know when a legacy payroll system or a classic game will demand it.
