It is odd that you are seeing a dialog saying it needs to be removed. Can you post a screenshot of that?
If a particular update version is already installed, regardless of the build number in the case of EA builds, you will see a message saying that it is already installed, you can then continue or cancel.
Why is it that you were trying to reinstall? As you called out the 64bit OS it may be the case that a 64bit JRE was installed and the JRE is not working in the 32 browser. I mention this as this is a common case. Really only IE has a 64bit browser for Windows, Chrome and Firefox are do not provide production 64bit browsers and thus the 64bit plugin will not run in those browsers. Windows 8 as a bit more of a hurdle as Java must be run on the desktop rather then the start screen and the 32bit browser, as I recall, is the default. Java.com will not provide the 64bit JRE unless a 64bit browser is being used for just this reason. Here are a few links that cover this:
You can obtain the 32bit JRE from https://www.java.com/en/download/manual.jsp
To complete the uninstall there are some steps you can try this first:
Only if the above does not work... registry changes, be careful, back up the registry!
Thank you for the info and the links. I had to try reinstall Java because Eclipse complained it could not load the JNI shared dll librsry c:\program files...\jvm.dll. I can not provide a scn capture of the error msg since the forum does not allow to attach files to a post.
I did apply the Microsoft utility ( Fix problems with programs that can't be installed or uninstalled)
but with no effect. I then searched the uninstall keys in the registry, as explained in (https://www.java.com/en/download/help/regkey_addremove.xml) and deleted 2 keys, but this did not help neither.
