The Lync 2010 client must be installed by using the client executable file.

Note The initial installation of Lync 2010 on a supported Windows client creates the Lync.msi file in the following locations:

%program files%\OCSetup
%program files(x86)%\OCSetup

The Lync.msi file can be used to deploy the Lync 2010 client by using the local and automated deployment methods that are described in the "Symptoms" section.
