Created Unassigned: Error after installing 2010SP2 in Updates Folder [20197]

I received the following error when doing a 2010 server installation including SP2 in the updates folder.


Exception : System.Management.Automation.ParameterBindingValidation

I found the issue at like 1093 of AutoSPInstallerFunctions.ps1 . The following line:

```
$sp2010LPServicePacks = Get-ChildItem "$bits\$spYear\Updates" -Name -Include oslpksp2010*.exe -ErrorAction SilentlyContinue | Sort-Object -Descending
```
Returned a collection with a single empty string instead of an empty collection. This caused a call to InstallSpecifiedUpdate in the loop below with an empty string, which caused the installation to bomb.

Adding the Null/Empty string check in the loop (see below) resolved in the installation issue.

```
foreach ($sp2010LPServicePack in $sp2010LPServicePacks)
{
if (-Not ([System.String]::IsNullOrEmpty($sp2010LPServicePack)))
{
InstallSpecifiedUpdate $sp2010LPServicePack ""
}
}
}
```
