Microsoft MSSQL installer seems to be confused and believe that there is an previous instance of MSSQL on the server. Microsoft MSSQL installer seems to believe that the installation of MSSQL on this machine would not change any settings or install anything new or change the configuration. 
It is unclear whether customer utilize MSSQL for any other applications or Services in their organization on this machine. Caution should be exercised in this instance to prevent the possibility of any other application losing their data...
If they use MSSQL for any other application then an administrator should review the machine and determine if MSSQL or one of its components is installed on this machine and if it can be removed safely without losing any data. 
If they DO NOT use MSSQL for any other application or service then they should be able to remove any MSSQL component installed and then proceed with the EzParts installation. 

Remove any tools, components or other MSSQL installations from this machine Server (using Control panel > Add/Remove Programs) and re-run the installer, as that previous installation is not configured properly to allow MSSQL installer to determine what components are actually present.
