Deployment guidance

Verify target systems meet OS and update requirements.
Test installation on a representative machine before wide deployment.
For unattended installs, use command-line options:
- Example (silent):
```
NDP48-x86-x64-AllOS-ENU.exe /quiet /norestart
```
- Use /norestart to prevent automatic reboot; handle reboots via deployment system.
Use deployment tools as appropriate:
- Group Policy, Microsoft Endpoint Configuration Manager (SCCM), Intune, or other software distribution tools.
Monitor installation results and logs:
- Installer logs are generated in %temp% (look for files prefixed with “dd_” or similar).
Rollback/Uninstall plan: document how to remove or repair the framework if necessary.

Corrupt download — verify checksum where available.
Permission errors — run installer as Administrator.
Conflicts with in-use files — reboot into safe mode or schedule install on next reboot.

Why Use the Offline Installer?

The online installer (a 1-2 MB "bootstrapper") requires an active internet connection to download the necessary components during installation. The offline installer (often called a "standalone" or "full package") is a single, large executable containing all the required cab files. Its advantages include:

No Internet Required: Perfect for secure labs, industrial control systems, or remote sites.
Repeatable Deployments: You can store the same .exe on a USB drive or network share for dozens of machines.
Faster Bulk Installations: No per-machine download delays.
Troubleshooting: If the online installer fails due to proxy or firewall issues, the offline package bypasses those problems.
