I am trying to install Outlook 2010 Home and Business Trial onto my computer and keep receiving this error message. "There was a problem setting up Microsoft Office and Home Business 2010. This product must be installed to Q: Ensure that Q: is unused and try again." I don't have a hard drive lettered Q. Q is a removable disk. It is for a flash card of some type. What is the procedure to correct this problem? I am trying to upgrade from Office 2007. Thanks in advance.
