The logs are helpful, but incomplete. It looks like the desktop client, the Admin Console and Snapshot were successfully uninstalled. The Office log is truncated so i can't tell what happened.

To answer your original questions, uninstalling from setuplf.exe in Common Files relies on locally cached copies of the MSI. Sometimes those go missing for whatever reason (reclaiming disk space on a machine that's low on disk, for ex). So since there was not much to go on in your original post, uninstalling using a known good copy would be the first thing to try.

How are you determining that the uninstall failed? Based on the logs, uninstalling Office was still doing work 4 min in.

It doesn't ever fail it just hangs on uninstalling. The setuplf.exe just stays in the task manager at around 32k ram used and will bounce around slightly for as long as you want it to run.

If I run the uninstaller through the command prompt with the same switches and the same files as what are copied down from PDQ it works in less then a few minutes. Everything is uninstalled.

If it helps I can recreate that log if you like. But, it appears to be the same as the past logs it's generated. Perhaps it appears incomplete because I kill the deployment?

I've attached the logs from the successful manual CLI uninstall for you. Perhaps that will give you a better insight?

Also thank you for the info about the MSI's That makes sense about if they somehow get cleaned up for disk space or whatnot.
