While Microsoft provides a standard .NET Framework 3.5 web installer
, Windows 10 and 11 users often face challenges when trying to install this specific version without an active internet connection. Because .NET 3.5 is considered a "Feature on Demand," the most reliable offline installation method requires using the original Windows 10 installation media as a source. The Role of Installation Media
For Windows 10, the "offline installer" isn't typically a single
file but rather a set of payload files (CAB files) located within the \sources\sxs
folder of a Windows 10 ISO or USB installation drive. This folder contains the necessary bits that allow Windows to enable the feature without reaching out to Windows Update. Offline Installation Steps via DISM
