Convert Powershell ElseIf to Switch Statement

I am trying to take my powershell elseif statements and convert them to a switch statement to make my code more optimized, but am unable to figure out how to do so.

Any help would be greatly appreciated.

Code:

    If (Get-InstalledApplication -Name "%AutoCAD 2015%") {
    #Install AutoCAD 2015 Object Enabler 
    $exitCode = (Execute-Process -Path 'Civil3D_2015_OE_64Bit.exe' -Parameters '/s /v /qn,', -wait -passthru).ExitCode
    "The exit code for the Civil 3D 2015 OE is: $exitCode" | Out-File -Append -FilePath C:\Logs\PW-CE\install.log
    }
    ElseIf (Get-InstalledApplication -Name "%MEP 2015%") {
    #Install AutoCAD 2015 Object Enabler 
    $exitCode = (Execute-Process -Path 'AutoCAD_Architecture_MEP_2015_OE_x64.exe' -Parameters '/s /v /qn,', -wait -passthru).ExitCode
    "The exit code for the Civil 3D 2015 OE is: $exitCode" | Out-File -Append -FilePath C:\Logs\PW-CE\install.log
    }
    ElseIf (Get-InstalledApplication -Name "%Civil 3D 2015%") {
    #Install AutoCAD 2015 Object Enabler
    $exitCode = (Execute-Process -Path 'Civil3D_2015_OE_64Bit.exe' -Parameters '/s /v /qn,', -wait -passthru).ExitCode
    "The exit code for the Civil 3D 2015 OE is: $exitCode" | Out-File -Append -FilePath C:\Logs\PW-CE\install.log
    }
    ElseIf (Get-InstalledApplication -Name "%Civil 3D 2017%") {
    #Install AutoCAD 2015 Object Enabler 
    $exitCode = (Execute-Process -Path 'Civil3D_2015_OE_64Bit.exe' -Parameters '/s /v /qn,', -wait -passthru).ExitCode
    "The exit code for the Civil 3D 2015 OE is: $exitCode" | Out-File -Append -FilePath C:\Logs\PW-CE\install.log
    }
    ElseIf (Get-InstalledApplication -Name "%AutoCAD 2017%") {
    #Install AutoCAD 2015 Object Enabler 
    $exitCode = (Execute-Process -Path 'Civil3D_2015_OE_64Bit.exe' -Parameters '/s /v /qn,', -wait -passthru).ExitCode
    "The exit code for the Civil 3D 2015 OE is: $exitCode" | Out-File -Append -FilePath C:\Logs\PW-CE\install.log
    }
