Search installation fails in SharePoint Foundation 2013

Question

As you all know there is no direct way to create a search service application in SP Foundation 2013 but when I try to create a new search service app using the Configuration Wizard it gives me the below error message. Did anyone encounter the same error
before? Any suggestions on configuring search in SP Foundation 2013?
Sorry, something went wrong
The directory C:\inetpub\wwwroot\wss\VirtualDirectories\80 is already being used by another IIS Web Site.  Choose a different root directory for your new Web application.

Thanks Anil. But the issue is I wont be able to create a separate application pool for search using the configuration wizard. It doesn't give me an option to create one.
I was successful in creating the search service application using the powershell script that is shared below. Now everything works as expected. 
Start-SPEnterpriseSearchServiceInstance $env:computername
Start-SPEnterpriseSearchQueryAndSiteSettingsServiceInstance $env:computername
$serviceAppName = "Search Service Application"
$appPool=Get-SPManagedAccount -Identity "Contoso\SpFarmSearch"
New-SPServiceApplicationPool -Name SearchApplicationPool -Account $appPool -Verbose
$saAppPool=Get-SPServiceApplicationPool -Identity SearchApplicationPool
$svcPool = $saAppPool
$adminPool = $saAppPool
$searchServiceInstance = Get-SPEnterpriseSearchServiceInstance –Local
$searchService = $searchServiceInstance.Service
$bindings = @(“InvokeMethod”, “NonPublic”, “Instance”)
$types = @([string], [Type],
[Microsoft.SharePoint.Administration.SPIisWebServiceApplicationPool],
[Microsoft.SharePoint.Administration.SPIisWebServiceApplicationPool])
$values = @($serviceAppName,
[Microsoft.Office.Server.Search.Administration.SearchServiceApplication],
[Microsoft.SharePoint.Administration.SPIisWebServiceApplicationPool]$svcPool,
[Microsoft.SharePoint.Administration.SPIisWebServiceApplicationPool]$adminPool)
$methodInfo = $searchService.GetType().GetMethod(“CreateApplicationWithDefaultTopology”, $bindings, $null, $types, $null)
$searchServiceApp = $methodInfo.Invoke($searchService, $values)
$searchProxy = New-SPEnterpriseSearchServiceApplicationProxy -Name “$serviceAppName Proxy” -SearchApplication $searchServiceApp
$searchServiceApp.Provision()
