406 Client browser (IE10) does not accept the MIME type of the requested page

Running a web application I get a 406 Client browser does not accept the MIME type of the requested page when I try to open a crystal report.

I am running IIS 7 and IE 10. I am logging in to SSL protected application I go to run a report which works fine but when I got to view the report I get the above message. What might be the cause of this error?

Thanks in advance.

What version of Crystal?
Most are not compatible with IIS7.

Have you tried running IE10 in compatibility mode?

I've also tried to view the reports from IE 10 & 11 with same results.

What is the web application?

Have you spoken with the support for the application?

I have resolved the issue:

The browser is expecting the MIME type for ‘crystalreportviewers/promptengine-compressed.js’ file as
‘application/x-javascript, text/javascript’.

But in IIS, at Default Web Site/Application (Application) level the MIME type for .js file is application/javascript.
Once I made the change I was able to see reports.
