The two most common problems when getting started with RAD PDF are caused when:
* RAD PDF was not installed on the server using our installer, instead only the Web Control is deployed. RAD PDF requires access to its installed system service (the RAD PDF Service) as well as other resources installed and configured. Simply copying the RAD PDF Web Control to your server does not properly deploy these other components.
* SQL Server has not been properly configured. Most commonly, the Web Application is properly setup to connect to the database; however the RAD PDF Service is not properly setup as specified in the SQL Server Setup Guide. The RAD PDF System Service also must be able to access the database so that it can retrieve, process, and save common resources.
