  the mechanism of fastreport web is :
  1. returning html which contains anitmated progress picture and a syntax to call webservice via ajax/xhr script, to enable calling webservice, you need to attach :
  (note: MVC Razor style)
  @WebReportGlobals.Scripts()
  @WebReportGlobals.Styles()
  
  2. in web.config, you must set webhandler to enable webservice
  in system.web section:
  <httpHandlers>
  <add path="FastReport.Export.axd" verb="*" type="FastReport.Web.Handlers.WebExport" />
  </httpHandlers>
  
  in system.webserver section:
  <handlers>
  <add name="FastReportHandler" path="FastReport.Export.axd" verb="*" type="FastReport.Web.Handlers.WebExport" />
  </handlers>

  I have it all. On my computer works properly. On another dont' work (another server , the same application). Maybe IIS configuration is not properly.

  double check the IIS installation features from the control panel (Programs and Features -> Turn Windows Features on and off -> Internet Information Services -> World Wide Web Services -> Application Development Features).
  
  and
  
  application pool in IIS Manager, another reference : https://msdn.microsoft.com/en-us/library/aa560277.aspx

  Interesting.....are you using Web Farm and Web Garden architectures?
  
  from documentation :
  To use the FastReport report generator in a multi-server (Web Farm) or multi-processor (Web
  Garden) architecture there are additional requirements for creating special storage for data
  synchronization between WebReport objects.

  I know where is the problem. When is set application pool on 'Classic' mode , FastReportHandler isn't set on IIS in mapping service( isn't read from web.config ).
  It have to be 'Integrated' mode. But why isn't work on 'Classic' mode?

  Read this : https://blogs.msdn.microsoft.com/tmarq/2007...-preconditions/
  
  IIS uses http handlers from both <system.web><httpHandlers> and <system.webServer><handlers>.
  
  The solution is add precondition: integratedMode, therefore, if you use 'classic mode', IIS will not use handler with precondition 'integratedMode'
  

    <system.webServer>
      <handlers>
        <add name="FastReportHandler" path="FastReport.Export.axd" verb="*" type="FastReport.Web.Handlers.WebExport" preCondition="integratedMode,runtimeVersionv4.0" />
      </handlers>
    </system.webServer>

  You have right. It's work. I had to be added <validation validateIntegratedModeConfiguration="true" /> in 'classic mode' .
  

  <system.webServer>
      <handlers>
        <add name="FastReportHandler" path="FastReport.Export.axd" verb="*" type="FastReport.Web.Handlers.WebExport" preCondition="integratedMode,runtimeVersionv4.0"/>
      </handlers>
      <validation validateIntegratedModeConfiguration="true" />
    </system.webServer>
