How to: Set Report Builder 1.0 as the Default ClickOnce Report Builder Version
SQL Server 2008 R2 provides a ClickOnce version of Report Builder 3.0 in addition to the standalone version released in the SQL Server 2008 R2 Feature Pack. ClickOnce is a Microsoft technology for deploying Windows applications. ClickOnce lets users install and run a Windows application such as Report Builder 3.0 by clicking a link on a Web page. Users can install and run Report Builder 3.0 from Report Manager or a SharePoint site.
By default, the ClickOnce application opens Report Builder 3.0. To change the default to Report Builder 1.0, you must update the value of the Custom Report Builder URL field in Report Manager. If you are opening Report Builder from a SharePoint site, you must update this field in SharePoint Central Administration.
Report Builder 2.0 is not compatible with SQL Server 2008 R2 report servers.
