What needs to be cleaned so that the installer understands that there is no JDK on the computer?

Question

Java

When I try to install the JDK, I get a message that there is this version of the JDK that I want to install. The fact is that I first installed this version, and then deleted the folder with all versions of the JDK, so that later I could reinstall only the version that I needed, but apparently it was necessary to delete it through "uninstall". What needs to be cleaned so that the installer understands that there is no such version of the JDK on the computer (and there is no version at all)?
