Having trouble installing JDK

I tried setting this solution found on the website: Select Start menu > Computer > System Properties > Advanced System Properties. Then open Advanced tab > Environment Variables and add a new system variable JAVA_HOME that points to your JDK folder, for example C:\Program Files\Java\jdk1.7.0_21.

But I still get an error saying: The environment variable JAVA_HOME (with the value of C:\Program Files\Java\jdk1.7.0_21) does not point to a valid JVM installation.

I would really appreciate if anyone could help me with this because it took 4 hours for me to download and I really want it to work. Thanks in advance!

Could you verify a few things? Are Android Studio and Java either both 32 bit or both 64 bit? Did you set the environment variable as a System variable or a user variable? What version of Android Studio are you running? What OS are you running(also is it 32 or 64 bit)? I found a few stackoverflow posts with sitautions similar to this here and here. Please let us know if any of this helps, if not, we can try providing more assistance.

Hi James, I actually somehow installed JDK before I checked back on this but I get the feeling I'm still going to run into problems because there were a bunch of errors I encountered while trying to install it. I can open Android Studio now but I'm still in the process of testing it out. Thanks for taking the time to answer my question though.
