Illarion.org

it won't even let me install the game on my computer using offline instaliation...it says that java 1.5 has not been found...the java site says that i have java on my computer...i don't know what the problem is...it has been doing this for about 3 days.

will illarion only work with java 1.5? i just downloaded the newest version of java and it won't work...do i need 1.5 or is there something else that i can do?
