Cleaning Registry Entries
Then, clean out Java-related registry entries. This might seem scary, but a good registry cleaner can do it safely. Always back up your registry before starting.
This step removes any old Java files that might block the new installation.
Running the New Installation

Also, a simple reboot can often fix small issues that stop Java from setting up properly.
