It looks like you need to manually update the module path.
Make sure this directory exists on the computer.
C:\Program Files (x86)\Microsoft SQL Server\110\Tools\PowerShell\Modules\SQLPS

If this happens, run
$env:PSModulePath = $env:PSModulePath + ";C:\Program Files (x86)\Microsoft SQL Server\110\Tools\PowerShell\Modules"
Then check if the SQLPS module is in the list of available modules using
get-module -listavailable
