Issue
In a Niagara R2 Enterprise Server station, the DDE Service is installed but it is not communicating to the 3rd-party product.
Environment
- Niagara R2 Enterprise Server station
- DDE Service
Cause
No longer support the DDE service.
Resolution
The DDE driver is an old driver that Tridium did not update over the years. Its last supported operating system is Windows 2000. Product Support Services does not support this driver and Tridium does not recommend using it for any new installations.
