Because the installer calls home to a server, privacy-conscious users often worry about telemetry. While most vendors use this only to verify the download, there is a potential for data collection regarding the user's hardware and OS environment.
The adoption of web installers is driven by several key benefits for both developers and users: Many web installers (like the Microsoft Visual Studio
The primary bottleneck of this approach is its requirement for a consistent network connection. If your network drops or suffers from high latency midway through the process, the installation will stall or corrupt. 2. Air-Gapped and Enterprise Restrictions
