I'm not sure why an in-place Upgrade or Repair Install is being considered here.
If the only issue is a partition which was deleted that held the Office program you want to recover, then boot into free Partition Wizard bootable CD to run the Partition Recovery Wizard which should recover intact the D partition.
You'll need to clear anything you replaced it with so it can be restored once the Wizard finds and offers to Recover it.
