Cannot Install 9.5 " The MSI has failed"

Hello Everyone,

I am struggling with getting sophos 9.5 to install on one of my clients.  It is a windows XPS SP3 machine. It had Sophos installed but quit updating all at once.  Looking at the log is says " Failed to install SAVXP: The MSI has failed".  I have tried removing all the sophos software and manually deleting every sophos folder I can find. I have tried pushing the install from the console, and installing manually.  I have also re-registered the windows installer service.  Does anyone have any ideas?  Thanks for any assistance you can give!!

I would post the install log, but its beyond the 20,000 character limit. However I read on the forum that the pertinent information is usually near the "value 3" lines so I have posted them below.
