I have a new install of CF 9 (right now as trial version) running on Windows Server 2008, 64 Bit, IIS 7. Overall the installation is successful and I've updated to 9.01. However, I have a problem with the CF Administrator site that is on the surface annoying and leads to a lack of trust that CF is indeed working properly. When I open the CF Administrator site, it functions be there are no graphics. If you open any graphic, for instance the Adobe ColdFusion Administrator logo, the graphic does not display.
Opening the graphic URL in a browser yields this error:
Error Summary
HTTP Error 500.19 - Internal Server Error
The detailed Config Error message is: Cannot add duplicate collection entry of type 'mimeMap' with unique key attribute 'fileExtension' set to '.air'
I found references to this error on other forums and sites, but none of those threads lead to any solution. I have completely uninstalled CF, re-installed, and removed and even re-insalled ASP.NET v4 (one of the issues mentioned in other threads) to no avail.
Any ideas or suggestion would be much appreciated.
