Exchange 2010 server sp1 kurulum hatası

Değerli Üstadlarım ve hocalarım;

 Sizlere takıldığım bir yerde soru sormak isterim. VMware 7 üzerine windows 2008 r2 (64bit) server kurulu. ve bunun üzerine exchange 2010 sp1 server kurulumu yaparken hata alıyorum çok araştırdım forumdaki herşeyi okudum uyguladım. her seferinde sıfırdan başladım ama olmadı. tüm güncelleştirmeleride şimdiden teşekkürler.

 hata ayrıntısı:

 önce şöyle bir uyarısı var;
