Applies to:  ReCrystallize Pro Web Wizard for Crystal Reports, version 14.0, IIS 8

Synopsis:

When attempting to view a Crystal Report in a web browser using ReCrystallize Pro's ASP.NET option, the report viewer appears but does not prompt for parameter values as expected.  The report page within the viewer appears blank.

More Information:

The report viewer uses Javascript (.js) files to prompt for parameters.  IIS 8 (Windows Server 2012 and Windows 8) uses a different MIME type setting for .js files than previous IIS versions used.  A 406 (not allowed) error is generated when the viewer attempts to prompt for the parameters, but may not be visible in the browser.

Solution:

In IIS Manager, change the MIME type for the .js extension to "application/x-javascript" instead of "application/javascript"
