Does Adobe still sell licenses for coldfision 2018, 2016 and CF11? if so where can i find the install files for these, the DL link is mising from adobes site. you can get the add on service and API but not the main server...
Adobe sells only the most recent version of any of its applications. In your case, that's ColdFusion (2021).
Beware of people DMing you offering to sell you older versions or representing themselves as Adobe employees with offers to "help you" get older versions of software. They are generally scammers.
It is possible to get used versions of some Adobe programs, but the license must be transferred from the old owner to you. If the seller isn't willing to do that, don't buy from them as (again) it is likely to be a scam. eBay is unfortunately rife with them, and I strongly recommend against trying to buy used software from the eBay site.
