I have the same problem: a fresh install of W7/64 and downloaded javaRa 2.0 & new defs. My account has admin privileges and am using the RunAsAdmin option. My system has jre 6v35. When I ask to uninstall, the pulldown is not populated. When i ask for current version, it knows I have 6v35. When I ask it to ‘download and install the latest version’, it install 6v26 and leaves 6v35. When I again ask to remove versions, there is still no population of pulldown. Both versions will uninstall with W7’s Uninstall Programs, but I was hoping to have this for cases that are not well-behaved.
