I have been using Office 2003 Professional for ages. However, since yesterday everytime I try and go into Excel a box comes up called 'Browse for Folder' and in the box it reads 'Please locate the program install directory'. When you click on 'cancel' another box comes up called 'Vision'. The narrative in this box reads 'The program directory was not located. The program will now abort'. When you then click 'OK' it opens up Excel.

Any ideas anyone.
