1. Install to Winsxs Directory using MSMs merged into app setup.
Merge Modules that install the DLLs to WinSXS can be found under Program Files\Common Files\Merge Modules. These MSMs can be merged into the app setup. Various Setup authoring tools are available and allow merging MSMs. Please refer to the Authoring tool documentation to determine how to merge the MSMs. Merge the required MSMs into the app setup.
Pros : Only deploy the assemblies that the app depends on.
Cons : App has to have its own setup, requires admin rights to install

2. Private Assembly install under app directory.
The VC Libs files can be installed under the app directory as a private assembly. The files required for the private assembly are under <VS install path>\vc\redist. Copy the required sub directories to the app directory.
Pros : App does not have a setup, xcopy deploy, Non admin install, Select the assemblies that the app uses, run from share
Cons : Not suitable when a product installs multiple binaries and these are installed in various directories (assembly has to be duplicated under each directory)

3. Install to Winsxs Directory using vcredist*.exe.
vcredist*.exe found under <VS install path>\sdk. These are standalone exe that installs all the VC libs to WinSXS directory. It installs only the retail versions of the DLLs.
http://msdn2.microsoft.com/ms235291(en-US,VS.80).aspx
Pros : App does not require a Setup, Has to be installed on the machine once and multiple apps can use the central version.
Cons : Installs all the VC Libs DLLs irrespective of whether they are used by the app, requires admin rights to install
