Had first Boot Camp installed with Win 7 64 9 Parallels has it 'own Boot Camp' made. Windows must be activated in this case, new to Microsoft because Parallels changed several components. An automatic activation is no longer possible, you have to do the annoying procedure by telephone, ie, type in endless rows of numbers and letters on the phone as well as on the keyboard. If you have not understood what or typed incorrectly, you start probably from the beginning (with me hath worked the first time around). Parallels is working properly, but Min.16 GB RAM are recommended by my 16 GB when using Parallels only 7 to 9 GB free (Win runs with me with 4GB). You can switch to the F6 key between Mac and Windows. Even older games without errors (eg Siedler 4), newer games running at medium settings (eg, PES 2013 is without jerking throughout the 27 'screen playable). My computer: Mac Late 2013; 3.4GHz i5; 16GB of storage; 4GB graphics card .; 512GB SSD.
