FYI, I figured out what the problem was. To answer my own question, it is compatible and works correctly.
What I had to do was go into InstallShield Pro 12 and find the component, and set one of the options on the component to disable Registry reflection, as it WAS putting the registry options in the SysWow64 node. Disabling the reflection keeps the registry data in the 32bit portion.
