We have seen that some of you have not been able to get the web server connector working after applying update 14.
We did our investigation and following is our finding.
The connector binaries of ColdFusion 10 update 14 are built on top of VC++ runtime 2012 update 4.
Installation of VC++ runtime requires admin privileges. If the ColdFusion service runs as administrator or system account, the update itself install the VC++ runtime as this account would have installation privileges.
If your ColdFusion service account is not running as administrator or system account, applying the hotfix from administrator can't install VC++ runtime and you will get "500 internal server error" after configuring the connector.
In this case, you need to manually install VC++ runtime 2012 32-bit and/or 64 bit depending on whether Web server is 32-bit or 64-bit.
You can download VC++ runtime here at:

When you install hotfix manually, administrator privileges are enforced and so the installation of VC++ runtime is automatically taken care by the updater.
