The SDK install location should only use the major.minor version number of 2.1 in the name. So rather than "Program Files/Oracle/JavaFX 2.1.0 SDK" it should be "Program Files/Oracle/JavaFX 2.1 SDK".

Note that the bundle names and registry keys should use the full major.minor.micro version of 2.1.0, which should also show up in the Windows 7 "Programs and "Feature" list.
