MasteringEdition with Cubase 6.5 64 Bit and Windows 7 64 Bit

Anybody knows how to install the MasteringEdition on a Cubase 6.5 64 Bit Windows 7 64 Bit System?

For the WaldorfEdition I found in a a forum a workaround via exporting registry strings from an old running installation into windows 7. Maybe someone knows a workaround like this?
