latest Java sre cant be installed

so i have a RuneScape account and i want to play on it in the fancy new HD mode.
thing is i can play it in lower detail, but when i try to un HD it says i need a more recent Java version

ok everything cool i download the latest version
unpack/install/whateveritdoes the bin file
i try to run the created rpm like the manual says but then the console tells me:
Preparing packages for installation…
package jre-1.6.0_07-fcs is already installed

wth?
i tried again to play HD after this msg but it still says i need to update and redirects me to Java.com

that is because the package is already installed, you want to upgrade the package not install it, rpm considers this differently

use -U

rpm -U /path/to/jre-1.6.0_07-fcs.rpm

use the acual path to the file and actual file name

if you get HD to work plz tell me i had it working once, but i cant get it to work again

you should know that there are no recorded cases of HD mode working on linux without a NVIDIA, ATI, or INTEL graphics card

so basically you need a good/moderate graphics card
