When trying to open reports from an assembly in the Standalone Report Designer so that they can be imported, if there are types that inherit from Telerik.Reporting.Report that do not have a parameterless constructor, this will cause an exception as it is required for the report types to have such a constructor, otherwise, the wizard cannot import them into TRDP.

In this scenario, the report types that do not have a parameterless constructor should be written to the trace or in the exception message dialog so that the user can see which are the problematic types and correct them.
