Win2008 server: Failed to download Chart ProtocolError - NotFound (404)


Recommended Posts


We are trying to get ChartFX62 working on a Win2008 server but are getting the following error.

 Failed to download Chart ProtocolError - NotFound (404)

 We have reviewed the following articles below that seem similar to the older Win2003 server issues.  We have created the ChartFX62 application in IIS 7.0 and set read/write permissions to the ChartFX62 folder to IIS_WPG, IUser_MachineName and Network service.

We added .lic and .chw as new MIME types for the ChartFX62 application.

Please let us know what we should try next.



There are some known issues regarding ChartFX for .NET and Windows 2003 Server; below, please find some articles that refer to that topic:




Due to the "lock down" nature of Windows 2003, IIS is configured to not serve any unknown file types; as a consequence, IIS may return 404 - File Not Found for some of the file extensions we use with our component, or a broken image. You will need to add the MIME types for your application. The last two articles talk about ChartFX Internet 5.5 but they also apply to ChartFX for .NET.

I went ahead and uninstalled and installed the version you suggested above.  However, I still got the same error.

After some investigation I noticed the following web.config in the directory: ChartFX62\Temp

<?xml version="1.0" encoding="UTF-8"?>




  <remove fileExtension=".chw" />




I guess at some point during troubleshooting and testing this web.config must have been created while changing MIME Types in IIS.

When I removed this web.config file from the ChartFX62\Temp charting started working!

In any case, thanks for your help!
