ChartFX.NetIEClient.Loader.dll 404.2 - Not Found


Recommended Posts

Hello, migrating the installation from an old (2003) server to a newer 2012 server, on a site testing its failing, and looking at the trace of what is loading in the site (F12 in IE) it shows a 404 not found error on ChartFX.NetIEClient.Loader.dll. 

I tried putting all permissions to the file (to everyone) but still nothing changed. I tried with a test html page on the same folder and it works ok.

Is there a step I'm missing?

Thank you

Thanks for the reply. Yes, the log shows its trying to access it but gives 404.2 with

"The page you are requesting cannot be served because of the ISAPI and CGI Restriction list settings on the Web server."

The file and path exist, but I guess its missing permissions or something to respond that file.... not sure what

I added the dll directly in the isapi/cgi exceptions, and now I get a 500 error


ModuleName: IsapiModule 


HttpStatus: 500 

HttpReason: Internal Server Error 

HttpSubStatus: 0 

ErrorCode: The specified procedure could not be found.  (0x8007007f)

In the error IIS is trying to execute this DLL

As I said you want to configure IIS to only "serve" these files for download, if you manually added it to ISAPI/CGI, you must undo these changes.

I would recommend you manually create a new virtual directory for testing, copy one or more DLL files and check if you point your browser to one of the DLLs if IIS returns the file or if it tries to execute it.

Thanks for following up.

I removed the ISAPI/CGI and I get an "404.2 - Not Found" error

The MIME Type for .dll is set to application/x-msdownload

Not sure what else to set for it to be downloadable and not tried to be executed.
