Notes about the ROI file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The ROI file type is primarily associated with 'e.Report Designer' by Actuate Corporation. Actuate e.Report Designer Professional is a development environment with which professional developers can create tightly integrated, highly flexible enterprise reports for any Web-enabled application. e.Report Designer Professional lets developers design reports that access any data source, deliver information in any format, and present reports in any conceivable layout, no matter how graphically complex. An instance file is what the user sees when the report is running in the Actuate window.
