When you used Revo Uninstall to remove remnanats, are you sure you did the following?
1. Selected Uninstall from within Revo
2. Chose Yes to uninstall Office.
3. Once the Uninstall was complete, selecting Advanced from within Revo screen and then clicking Scan.
4. When the scan finishes, clicking Delete BEFORE clicking Next. You will likely be prompted to click Delete a second time as well for any remaining folders.
Just want to confirm as this has always worked for me.
