Comments: First i think you have to update both systems, WSUS AND WPP. In WUS-FAQ No. 44 you can see how old your WSUS-Installation is. http://wsus.de/faq You need 2 Updates more: WSUS 3.0 (SP2) + KB2720211: Build 3.2.7600.251 WSUS 3.0 (SP2) + KB2734608: Build 3.2.7600.256 WSUS 3.0 (SP2) + KB2828185: Build 3.2.7600.262 WSUS 3.0 (SP2) + KB2938066: Build 3.2.7600.274 After this pls use the actual WPP Version and try again.
