Analysis office client add-in installation via SAP GUI Installation server

Hi,

I need to install ANALYSIS OFFICE CLIENT 2.6 (AO) via SAP GUI Installation Server.

But on several workstations we have error about Visual Studio 2010 Tools (VST) prerequisites.

I checked that workstations, I executed AO installation directly, and it's true, AO cannot install because VST missing on workstation.

How install VST before installation AO?

Thanks...
