Incremental synchronisation with AUSST

Hi

I've built an internal update server using AUSST for updates. I want to set a script to run the updates incrementally without being logged in - assumed a powershell script run as a scheduled task would be the best option. The script I've written is below:

$body = "C:\Program Files (x86)\Common Files\Adobe\OOBE\PDApp\CCP\utilities\AUSST\AdobeUpdateServerSetupTool.exe"--root="D:\Updates\Adobe" --incremental |Out-String

"Updates are complete." -Nonewline -Foregroundcolor Green

-From email@domain -To email@domain -Subject "Adobe AUSST Updates" -Body $body -SmtpServer "mailbox.domain.local"

I get the following error when running this though:

At line:1 char:117

+ ... tupTool.exe" --root="D:\Updates\Adobe" --incremental |Out-String

+                    ~~~~~~~~~~~~~~~~~~~~~~~

Unexpected token 'root="D:\Updates\Adobe"' in expression or statement.

At line:1 char:9

+ $body = "C:\Program Files (x86)\Common Files\Adobe\OOBE\PDApp\CCP\utilities\AUSS ...

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The '--' operator works only on variables or on properties.

    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException

    + FullyQualifiedErrorId : UnexpectedToken

Can anyone see where I'm going wrong? I've not done an awful lot with Powershell so excuse me if I'm doing something daft.

Cheers.
