Scenario: I recently had to uninstall office 2013 because it use to start configure word or outlook whenever I start word or outlook. After hours of wasting time (well it's a Microsoft product, so ....) I uninstalled it and started installing office 2010 which i had earlier but it started giving me errors
After again wasting hours on this in my office the following worked for me.
right click on the following folder
C:\Program Files\Microsoft Office
On the Properties window, select the Security tab
give full permissions and click ok, click ok.
The installation should proceed perfectly.
