Error when Running Report

[Donald]

When I try to run the report on a specific machine, I am getting the following error message. This program runs locally, and on other servers just fine.

System.ArgumentException: Unable to find the requested .Net Framework Data Provider.

Full Error message and call stack:

Telerik.Reporting.Processing.Data.SqlDataSourceException: Unable to establish a connection to the database. Please,

make sure the name is correct and the connection string settings are present in the configuration file of your application. --->

Hello Donald,

You can test if the used in the connection string data provider is properly installed and registered on the server by creating a simple report with the Standalone Report Designer on the machine. If the provider is not listed, please reinstall it and verify it is registered correctly.
