ColdFusion 11 installation unsuccessful

Question

I installed ColdFusion 11 Developer version (downloaded from Adobe site 3 months trial) on Windows 8.1 and IIS7. I got this error when trying to open the ColdFusion administrator (see below). Is there a step by step example on how to fix this?

Answer 1

Remove the MIME type from web.config

<mimeMap fileExtension=".air" mimeType="application/vnd.adobe.air-application-installer-package+zip" /> and save the file. Restart IIS and that should fix the issue.

Answer 2

Removing the mime type from the web.config was enough and its remaining content was all right in our case; please note that this was related to the ColdFusion sites in general and not with the ColdFusion Administrator. The problem started after upgrading from ColdFusion 10 (update level 11) to 11 (update level 0) (on IIS 7.5, Windows Server 2008 R2), having changed the connectors from old version to ColdFusion 11 (as the installation document indicates at "Verify your IIS configuration" section). It had two positive effects:

• the cascading styles started being delivered correctly
• the 500 Internal Error on the IIS "Windows Authentication" directories stopped appearing (we regarded also https://forums.adobe.com/thread/1031711)

Answer 3

Was it an upgrade? I had a similar problem. I had to manually disable my Coldfusion 9 handlers.
If your previous Coldfusion handlers are still active, and you don't want to remove them until you are confident 11 is stable you can deactivate them in the web.config file.

<handler>
  <remove name="AboMapperCustom-somenumber"  />    
  <remove name="AboMapperCustom-anothernumber"  /> 
</handler>

The web.config file should be found in the root directory of each website.

This happened to me as well after updating Coldfusion 11 to the upgrade 2 (patch), somehow it reads web.config file under C:\Coldfusion11\cfusion\wwwroot What I did was simply rename the web.config to something like web - error.config IIS will skip this file and run just fine. When the file exists, I couldn't even access MIME configuration from the IIS Manager, so removal or rename of that file was the solution for me. It's also discussed in : http://blog.immanuelnoel.com/2014/09/22/busting-the-http-error-500-19-on-coldfusion-11-iis/ and probably a bug under initial coldfusion configuration.
