Mismatching ColdFusion ISAPI Filters and Handlers Enabling IIS detailed errors provides more detailed information about what is failing. It allows you to check if any pathing is being incorrectly pointed to the wrong ColdFusion version.


To resolve these issues, follow these steps:

  1. Check Coldfusion Handler Mappings: Ensure that the correct Coldfusion connector pathing is specified.
  2. Verify Virtual Directories: Confirm that virtual directories are correctly configured.
  3. Inspect ISAPI Filters: Make sure ISAPI filters are properly set up.
  4. Review the web.config File: Ensure that it does not specify an older path that might conflict with current configurations.

By carefully checking these areas, you can identify and solve common problems related to Coldfusion and IIS integration.

Corrupted Java version

Symptom and Description

Symptom Description
ColdFusion Not Fully Starting Up When attempting to start ColdFusion, it either fails to launch or only partially starts. A key indicator of a partial start is observing in the Task Manager that it is only reaching 50MB of RAM usage, suggesting that the service is not fully operational.

How to Confirm the Issue

  1. Open Command Prompt as Administrator: Start by opening a Command Prompt window with administrative privileges.
  2. Execute the Startup Command: Run the following command, replacing [ColdFusion version] with your actual ColdFusion version directory:
C:\[ColdFusion version]\cfusion\bin\cfstart.bat

This command initiates the ColdFusion startup process and displays the progress, helping you identify at which point ColdFusion encounters an error. Pay close attention to any errors related to a Java component, as illustrated in the example screenshot below. Such errors indicate a corruption in the Java installation.


To resolve Java-related startup issues with ColdFusion, follow these steps:

  1. Download the Correct Java Version: Visit the Adobe ColdFusion downloads page and select the appropriate Java version for your ColdFusion setup. You can find the downloads at the following link: Download ColdFusion updates, add-ons, and developer tools (
  2. Reinstall Java: After downloading the correct Java version, proceed to install it on your system.
  3. Update jvm.config: Ensure the C:\[ColdFusion version]\cfusion\bin\jvm.config file is updated to reference the correct path to the newly installed Java version.
  4. Restart ColdFusion: With the correct Java version installed and configured, restart ColdFusion to apply the changes.

By following these steps, you should be able to address and resolve the issue preventing ColdFusion from fully starting up.
