Why is this keyword "NEW"? Microsoft periodically re-signs the offline installers with new SHA-2 certificates and updates the servicing stack to ensure compatibility with Windows 11 2023 and 2024 updates. The "new" version ensures you aren't downloading a corrupted 15-year-old file.
If you do not have internet access, you can install it using a Windows installation ISO or USB. Microsoft Learn your Windows ISO or insert your USB drive (e.g., as drive Command Prompt as an administrator. Run the following command (replace with your actual drive letter):

Once you have downloaded the official installer (let's assume you chose the offline .exe ), here is how to avoid common pitfalls.
Unlike newer versions of .NET (such as 4.8 or the modern .NET 5/6/7/8), the .NET Framework 3.5 is not a standalone layer. It is built upon the Common Language Runtime (CLR) of version 2.0.
However, the act of downloading and installing .NET Framework 3.5 on a modern system is not without friction. Users often encounter error code 0x800F0906 or 0x800F081F, indicating that Windows cannot find the source files. This typically occurs because the installation attempts to fetch files from Windows Update, but corporate firewalls or Group Policies block the connection. The solution—and the reason the query remains technical—involves using the Deployment Image Servicing and Management (DISM) tool. An advanced user will download the official ISO, extract the sxs folder, and run the command: DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:D:\sources\sxs . This surgical approach bypasses the need for a "NEW" web download entirely, using the original, digitally signed feature-on-demand media.
