2003 Excel and 2007 Trial Version Excel
 

I downloaded the 2007 trial version of Microsoft Office. Now my trial is
over and I reloaded my 2003 version. But it will not let me remove the 2007
trial version. Also when I go into my 2003 Excel a Window Installer box
comes up that says Preparing to install and this stays on for about 5 minutes
before it goes away. I know that I should not have downloaded the trial
version but I did. Can someone please help me. I have Windows XP and it is
my office computer. Please help!
