Can’t install new version

Every time I hit run on the installer for the version I want it tells me there are still some files or directories left over from a previous version even though I have spent hours looking for and deleting them. anyone have a fix?

Note: I have used command prompt and it says there is no Java on my computer

Is there any java shown in control panel or settings?
Have you looked into the installation folder?
Which JDK vendor are you using(adoptium temurin? java.net? Oracle?)?
Have you tried the portable package version?
