You need to configure Rumba and Document Viewer to work together.
Here is an overview:
- In Rumba, select options, api, hllapi, and a short name 'A' (for example).
- In the DVPC Emulator window, choose Remote, Configure Connection, HLLAPI to display the HLLAPI Configuration dialog.
- HLLAPI TYPE: Rumba
- Session ID: type A (from the example in 1. above)
- HLLAPI DLL filename: EHLAPI32.DLL
- Verify the Rumba directory that contains EHLAPI32.DLL is in the SYSTEM PATH for your operating system. The directory is usually PROGRAM FILES\WALLDATA\SYSTEM.
