I have just installed Windows Server 2008, SQL Server 2008 and VisualStudio Team Suite 2008, applied all updates, including hot fix KB956717. When I try to render any Reporting Services report via the /ReportServer URL or via the preview in the Business Intelligence/Visual Studio, I get:
"An error occurred during client rendering. Object reference not set to an instance of an object."
When I try to run a report via the /Reports (Report Manager) URL, I get:
"An error occurred during client rendering.
An error has occurred during report processing.
Could not load file or assembly 'Microsoft.ReportingServices.Modeling, Version=10.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxxxxx' or one of its dependencies. Access is denied."
