I keep receiving a "[FONT="]Error Code 0xC004E003" when ever i try activate my windows ultimate. Its the correct key but it just goes non-responsive then the error code comes up. Anyone one know how to fix it?[/FONT]
This just means that your Vista Product Key Number is showing as still being currently used. You will sometimes get this when you do a reinstall of Vista. Microsoft still thinks you have it running on the previous install.
You will just need to do a phone activation to activate your Vista.
In addition to Ferrisits link for Java, you can also get the Java SE Runtime Environment (JRE) 6 Update 10 from the link below if the other one will not work for you for whatever reason.
