After uninstalling MSO 2007 and a trial version of 2010, I am unable to install a MSO 2010 full version. I keep getting an error message reading that I am unable to install the New version due to still having the old trail version. I have done a regular uninstall, and I also have used REVO uninstaller. The 2001 version also the trail 2010 show NOWHERE on my PC (All programs). Can some one please help me. Thank you
