While installing VDA in a platform layer.  The VDA has MS VC redistributable pre-reqs and the pre-reqs were failing to install.

 

With App Layering both .net35 and any Microsoft redistributables belong in the OS layer.  The OS layer is the only layer you want to run Windows Updates on.  Even if they do work installed in other layers, they would not be getting windows updates. 

1. Add a new version to the OS layer
2. Install .net35
3. Install all pre-reqs for the VDA
4. If you also plan on using APP-V,  create a local administrator account called ‘CtxAppVCOMAdmin’.  Local accounts must be created in the OS layer, not the platform layer.  
5. Finalize the layer.

Once the OS layer has been updated, create the platform layer using the new version of the OS layer and install the VDA.

Problem Cause

The pre-reqs were failing because .net35 was not installed.
