### 6. Installation & Setup

System Requirements Recap:
- Windows 95/98/NT 4.0 with DCOM enabled
- CD‑ROM drive
- Sufficient disk space
- NuDAM modules connected to a serial port

Installation Procedure:
1. Insert the ADLINK All‑in‑One CD into the CD‑ROM drive.
2. If autorun does not start, manually execute `x:\setup` (where *x* is the CD‑ROM drive letter).
3. Select Software Package → NDS‑OPC from the installation menu.
4. Enter user information and a valid serial number. Without a valid license, the software runs in a 120‑minute demo mode.
5. Choose installation directory (default: `C:\Program Files\ADLINK\NuDAMOPC`).
6. Select installation type:
- Typical: Installs all components (recommended).
- Compact: Installs essential components only.
- Custom: Allows manual selection of components.
7. Complete installation and click Finish.

Post‑Installation Configuration:
- Verify that NDOPCSvr.EXE is registered in the system registry.
- Confirm that DCOM settings are enabled in Windows registry:
```
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OLE\EnableRemoteConnect = 'Y'
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\OLE\EnableDCOM = 'Y'
```
- For Windows 95, install “DCOM for Windows 95” from Microsoft or Visual C++ 5.0 CD.

Sample Program Setup:
1. Connect NuDAM modules (ND6060, ND6012, ND6021) to COM1 with addresses 6, 2, and 11 respectively.
2. Launch NuDAMExplorer.EXE and open Demo.adl configuration file.
3. Save configuration as Server.cfg.
