The standalone JavaFX launcher uses the windows registry to lookup the location of the JavaFX runtime. Because the installer only creates a registry key for the exact micro version -- 2.0.0 in the current release -- and because the launcher only looks for this specific version, the launcher will fail to locate the runtime when 2.0.1 or 2.0.2 is installed.

Even if we fix this in the launcher, it won't help apps compiled with 2.0 GA, since the class that does the registry lookup is compiled into the application jar file.
