Commented Unassigned: Script fails is no updates for Office Web Apps 2010 are found [20487]

Script fails if it's setup to install Office Web Apps but there aren't any updates in the folder. Checking $sp2010OWAUpdates for null (around line 1295 in 3.96) fixes the issue:

```
if ($xmlinput.Configuration.OfficeWebApps.Install -eq $true)
{
$sp2010OWAUpdates = Get-ChildItem -Path "$bits\$spYear\Updates" -Name -Include wac*.exe -Recurse -ErrorAction SilentlyContinue | Sort-Object -Descending
if($sp2010OWAUpdates)
{
foreach ($sp2010OWAUpdate in $sp2010OWAUpdates)
{
InstallSpecifiedUpdate $sp2010OWAUpdate "Office Web Apps Update"
}
}
}
```

I had this issue too, installing SharePoint 2010 Office Web Apps on a new server. However, my Updates folder had the Office Web Apps Service Pack 2 files in it. Still, it failed to install. Changing the lines above in AutoSPInstallerFunctions.ps1 fixed the issue.

My error details were:

--------------------------------------------------------------
- SharePoint 2010 binaries appear to be already installed - skipping installation.

- No language packs found in C:\Install\AutoSPInstaller\SP\2010\LanguagePacks, skipping.
- Currently installed languages:

- Looking for SharePoint updates to install...

- Script halted!
