I also downloaded some 'get rid of office2003'-tool from MS but that didnt really do it either.
SO, I deleted my entire office folder and the 'Office'-folders in the registry hoping it would 'reset' stuff, then I tried to reinstall office thinking it might uninstall afterwards. I then tried uninstalling it as per the usual way from the controll panel but it wouldnt let me now cause some. It sort of did but then a new problem arose where it complained on some other file. I googled for a sollution to that problem and changed a suggested registry value hoping that it would fix it. I downloaded it and ran it and afterwards my office2003 instalation complained about some.
I wanted to make my computer run a little more smoothly so I downloaded this 'cleaner program' (yeah I know, it's a big *bad idea* sign right there), anyhow.
