An error occurred while creating the IIS virtual directory

We attempted a exchange 2013 install in a coexistence scenerio. Getting the following error during the install process. Any ideas?

C:\Admin\Exchange2013CU2>setup /m:Install /Roles:ca,mb,mt /IAcceptExchangeServer
LicenseTerms /TargetDir:E:\Programs Files\Microsoft\Exchange Server\V15 /Install
WindowsComponents /DBFilePath:"M:\DB1\DB1.edb" /LogFolderPath:"L:\DB1\Logs" /Mdb
Name:"DB1"
