If you want to support ColdFusion scripts on the server, you should obtain a distribution package from Adobe and then install it on the server. Parallels Plesk Panel supports Adobe ColdFusion versions 6, 7, and 8.
After you have installed Adobe ColdFusion on your server, do the following:
Log in to Parallels Plesk Panel as administrator.
Go to Tools & Settings > Updates.
Click a link corresponding to the appropriate release version.
Select the checkbox corresponding to the ColdFusion support for Parallels Panel item, and click Install. Confirm the installation when prompted.
Once the selected components are installed, go to Tools & Settings > ColdFusion Settings(in the Applications group).
Specify the path to ColdFusion installation directory and click OK.
