We have a client machine that I'm not having any luck upgrading from 12.1.1101.401 to 12.1.2015.2015.
I constantly get an error stating that installer was interrupted before it could finish.
I've tried installing it from SEPM and as a standalone package. I've tried it as a domain admin and as a local admin. I've tried different install packages (removed option to add to Start Menu as well).
I haven't tried CleanWipe or uninstalling as I'm concerned once I get the software off, I might not be able to get it back on, leaving the client computer unprotected.
Any kind soul might be able to provide some direction?
