Dism /online /Add-Package /PackagePath:"C:\path\to\cabfile.cab" If you already have a verified offline installer (a .cab or a folder with microsoft-windows-netfx3-ondemand-package.cab ), follow these steps for Windows 10 64-bit: Step 1: Verify System Architecture Right-click the Start button > System. Ensure "System type" says 64-bit operating system, x64-based processor . Step 2: Extract the Offline Files Place the installer folder on your desktop or C:\temp . Ensure the path has no spaces. Step 3: Run DISM (Deployment Imaging Service and Management Tool) Open PowerShell or CMD as Administrator.

A: Microsoft does not provide a standalone .exe for the full offline package anymore. The DISM method with ISO or Microsoft Update Catalog is the official way. Avoid third-party dotnetfx35_full.exe websites—they are often infected. Part 10: Alternative - Using a Third-Party Repack (Proceed with Caution) Some reputable tech forums host repacked offline installers. Tools like "Microsoft .NET Framework 3.5 Offline Installer" by MajorGeeks or TechPowerUp have been verified by communities. However, always check SHA-1 hashes against Microsoft’s official reference. For enterprise environments, stick to the DISM + ISO method. Conclusion: Master Your Windows 10 64-Bit System The ability to install .NET Framework 3.5 offline on Windows 10 64-bit is an essential skill for IT administrators, developers maintaining legacy code, and power users running classic games. The online installer is unreliable; the GUI feature is broken by design. But with a Windows 10 ISO and a single DISM command, you can install it in under five minutes—no internet required.

.NET 3.5 runs as a separate runtime in memory. It consumes approximately 50–100 MB of RAM when active. On modern 64-bit systems with 8 GB+ RAM, this is negligible. Part 9: Frequently Asked Questions (FAQ) Q: Can I use the same offline installer for Windows 11 64-bit? A: Yes. The Windows 10 64-bit offline installer (via sxs folder) works perfectly on Windows 11.

A: Yes. The offline feature includes .NET Framework 3.5 SP1, which contains 2.0, 3.0, and 3.5 SP1 cumulative updates.
