New Post: Windows Update don't show update

Hi Guys,
i have a create software group "Net At Work". There exists 4 entries.
The dependences look like:
1) Microsoft Visual C++ 2010 x64 Redistributable - 10.0.40219
2) Microsoft Visual C++ 2010 x64 Redistributable - KB2565063 (Dependence: id 1)
3) Visual Studio 2010-Tools für Office-Laufzeit (Dependence: id 2)
4) Outlook Add-in 9.2.180.0 (32Bit) (Dependence id 3)

Programs 1 to 3 will be successfully installed. But the last one is not found by the windows update on the client.

Environment Server:

• Windows Server 2012R2
• WSUS
• Newest WPP Version
  

Environment Client:

• Windows 7 Professional, SP1, 64Bit
• Delete Windows Update Cache
• In the correct wsus group
  

P.S. The rollout from the newst Adobe Flashplayer was no problem.
