Part 2: Offline Installer vs. Web Installer – Key Differences
| Feature | Web Installer | Offline Installer |
| :--- | :--- | :--- |
| File Size | ~1 MB (bootstrapper) | ~51 MB (full package) |
| Internet required during install | Yes (downloads components on the fly) | No (all files are local) |
| Reliability on slow/spotty connections | Low – may fail mid-install | High – installs from local source |
| Multiple machine deployment | Impractical – each PC downloads separately | Ideal – copy to USB or network share |
| Official name | dotNetFx45_Full_setup.exe | NDP452-KB2901907-x86-x64-AllOS-ENU.exe (or similar) |
For Windows 7 64-bit, the offline installer is superior because Microsoft’s web installer often attempts to check for newer updates (like 4.5.2 or 4.6) and may fail due to expired certificates or missing OS prerequisites.
