NetApp Virtual Storage Console - VSC - in vCenter would not load unless you install 32-bit version of JRE for Java. As it turns out, Virtual Infrastructure Client uses 32-bit Internet Explorer to display pages inside Windows frames. So if you have installed 64-bit of Java, you would also need to download and install 32-bit of Java. Latest version 1.7 as of the time this post was written works with NetApp VSC version 2.0.1.
Hope this helps someone out there struggling to make VSC work on a 64-bit Windows 7 machine.
