Ok, now that both SQL Server and SharePoint Server are installed, we just need to set up PowerPivot for SharePoint and configure it. Easy huh? Well, it turns out it is pretty difficult to get it right. Installation is not difficult (this post) but the configuration is harder (the next post). Here is how to install PowerPivot. I used MSDN for the info:

Installing PowerPivot involves mounting the SQL Server Installation Media and calling the setup with the right parameters.

Function InstallPowerPivot
    Write-Log -Verbose  "Step 7: Install PowerPivot"
    $mountresult = Mount-DiskImage -ImagePath $global:pathToSQLISO -PassThru
    $driveLetter = ($mountresult | Get-Volume).DriveLetter
    $setupFile = $driveLetter+":\setup.exe"
    #Remove Service Account if it already existed
    Get-ADServiceAccount -Filter {Name -eq 'PP'} | Remove-ADServiceAccount
    $ppAccountName = "PP"
    $ppAccountNameFQ = $global:domainpart+"\"+$ppAccountName
    CreateServiceAccount -AccountName $ppAccountName -DisplayName "PowerPivot" -Description "Service Account for PowerPivot for SharePoint" -Path $global:path -Password $Password
    #do PP installation
    #trying with plain text pwd in call
    Dismount-DiskImage -ImagePath $global:pathToSQLISO
    Write-Log -Verbose  "If above an error is shown please check out C:\Program Files\Microsoft SQL Server\120\Setup Bootstrap\Log\Summary.txt"
    Write-Log -Verbose  "PowerPivot Installed"
    if ($global:DoAllTasks) {
        Set-Restart-AndResume $global:script "9"

Next time: configuring PowerPivot.
