Photoshop elements 12 Installation Failure - Shared Services

Question

Have tried twice to install (second time switching off my virus checker) get a failure to install shared services then it rolls back and uninstalls the programs.
Downloaded Support Advisor - Failed to find any issue.
Opened the "PSE12 STI Installer 12.0 10-26-2013.log.gz" file - gobbledygook to me but no obvious Error Code.  Last few lines imply successful installation (copied below)

Answer 1

Resolved using CHAT with an agent.  Seetharam was excellent.
Involved:
NAVIGATING the DVD, opening the PSE 12 folder (If you download then it should be in the Photoshop Elements folder).
RUNNING the ElementsSTIInstaller to install it then
NAVIGATING  to "C/Program file (X86)/Common file/Adobe/"
RENAMING the OOBE folder as oldOOBE.
AUTORUNNING the DVD
It is now fully installed....
