Thanks to "Parallels Desktop for Mac" I can finally use without much effort my Windows programs under OSX. The installation is very simple and well explained, I've installed with Boot Camp Windows 7 and this then transferred to Parallels Desktop. Then you can start directly from the OSX Windows programs as if they were installed directly on OSX, just awesome.
One there is to be observed: When you install Windows 7 under Boot Camp and this then imports in Parallels Desktop, you should first Windows 7 under Boot Camp Enable (via Internet) and connect with Parallels Desktop (phone). This is because the Microsoft emanating in this case from 2 different installations (1x normal, 1x virtualized).
Update: Meanwhile, I have to Boot Camp and Windows 7 completely waived only runs on OSX in Parallels Desktop. One can work with Windows applications as if they were installed on OSX, access the shared folder and drag and drop works perfectly.
