Resolving Common Installation and Configuration Issues

A full installation of ImageGear for Silverlight requires that Microsoft .NET Framework 3.5 SP1 and Microsoft Silverlight 2.0 be installed. If .NET and/or Silverlight are not installed, the ImageGear installer will guide you through those installations, and will not continue installing ImageGear until .NET and Silverlight are installed.

When the installation is complete, you will be given the option to register ASP.NET and re-register WCF with IIS. While this might not be required on your machine, Accusoft recommends that you complete these steps. Doing so will cause no harm and may simplify any future troubleshooting. See Post-Installation Procedures for details.

This section identifies some common installation and configuration issues, and provides solutions to these issues.
