your can bypass this check by adding the "/ignoreCondition" switch if you run it from the command-line, this switch also bypasses any condition check in the installer or the package. FYI, it checks: HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\RebootRequired Thx, works great now!
