Outlook 2010 may start only in safe mode

In this case, users that were using Office 2010 started to complain that their Outlook 2010 begun to start only in safe mode. Incidents opened about this outlook behavior started to grow rapidly. So, the number of opened incidents was very high in small period of time to think about some outlook add-in problem or outlook profile corruption. It was also symptomatic that this Outlook behavior started to occur after rebooting of the user's workstation. Also, it was notified that this Outlook behavior was happening on workstations that were members in first WSUS update group.
There was an update for Outlook 2010 with following KB3114409, that was approved for install on members of the first WSUS update group.
Microsoft has acknowledged this behavior, and removed this update as available update for downloading.
If this update is uninstalled from the affected workstations, Outlook will start normally (not in safe mode). After the confirmation that without this update Outlook runs as should, this update in WSUS was approved for removal.

A friend of mine has complained that he was unable to reinstall Office 2010 Professional on his laptop. The reason for his decision to reinstall Office 2010 was that latest updates for Office 2010 were failing to install on his Windows 8.1. The installer was failing to install the updates with generic code 1603. He has successfully uninstalled Office 2010 using Fix it from following location: http://office.microsoft.com/en-us/support/how-to-uninstall-or-remove-microsoft-office-2010-suites-HA104027750.aspx

Running the setup from Office 2010 installation CD, the installer was not detecting the old installation of Office 2010, and was trying to install new Office 2010 suite, but was failing with following error "Microsoft Office 2010 Professional encountered an error during setup" :
