Alrighty, first post here on BleepingComputer, so, please, do forgive me for lacking any necessary information for the problem. I will provide it post haste as requested.
Now, the problem. Java has gone nonfuntional with no warning or indication. There have been no changes, to my knowledge, made on my part. At this point I've deleted and reinstalled Java, previous updates, current,even old versions. All to the same resounding conclusion. Nothing is working. Not even broken in the useful way. Nothing happens. I click to start any Java-based application(Minecraft's Launcher, Java's command console, and any web based applets) and it'll give me the "Loading" mouse wheel for about a tenth of a second, then return to doing...nothing. I've watched the Task manager as I do it, nothing pops up and promptly dissapears. Nothing happens.
At this point, the only conclusion i've come to is maybe there's a registry error somewhere, but I've no idea how to check, or how to fix it.
I'm exasperated, I've been trying to figure this out for two days now, and frankly, I'm out of ideas.
Running Windows 7 64bit, Currently have Java Ver7Update45(Latest) installed and have reinstalled it quite a few times.
