Descargar Net Framework 3.5 Offline ((free)) May 2026

reg query "HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5" /v Install If it returns 0x1 , it’s installed. | Problem | Solution | |---------|----------| | Installer asks for internet | You used the web installer – use the offline dotnetfx35.exe link above. | | Error 0x800F0906 / 0x800F081F | Run the DISM command with Windows ISO (Method 2). | | “This app can’t run on your PC” | You’re on ARM or very old Windows – try compatibility mode or use Windows Features. | 🔹 Final Note The safest offline method for Windows 10/11 is Method 2 (DISM + Windows ISO) because it’s native and doesn’t rely on third-party downloads. The standalone EXE (Method 1) works universally but is larger and may require enabling the feature manually afterward on newer Windows versions.
