I install Java, but it Says I Didn't

[JustForNow]

Pretty much what the title says, I have a 32-bit Vista computer, so I'm guessing Chrome is 32-bit too, which is what I use. I had like 4 versions of Java, so I uninstalled them, not knowing why they were there so I can install 64-bit Java. Of course, I was stupid enough to forget that I also needed a 64-bit computer for that. I found out that it wouldn't work, so I reinstalled Java 7, but when I tested to see if I had Java, it said that I didn't. I tried reinstalling it, but no luck. Can anyone help me? I really need Java on the browser sometimes.
Oh, and Java's installed on my computer, but not Chrome, the browser I always use. Weird, huh?

not too sure about this, but check in the command prompt if you can: "java -version"
also, again not sure, see if you have JAVA_HOME is defined in you systems path
