How to activate the windows 7 operation system

CarltonWO

During step 4 of 4 in the installation a error pops up saying: "There was a problem setting up  Windows 7 Activation: There was a problem setting up  Microsoft Office 2007 Key. Try running Setup again."I have ran the setup several times. I uninstalled my previous trial version of Microsoft office 2007, but still have some Microsoft programs installed (language packs, Live ad in, and a few others), Im on Office 2010, Does anyone have any ideas?
