MS office keeps wanting to install a 'new feature' when I open up a Word or Excel document (the only Office applications I use on my Windows 7 PC). It will be OK for a day or two, then I will get the 'Office needs to install a new feature' (or similar) box .. This happens so often that I have copied the MS Office installation CD to my hard drive so that it can do it automatically: that way it's less of an annoyance.

Even so, does anyone know why this keeps happening? I've tried reinstalling Office (XP version, 2002) afresh, but that doesn't help. I have also installed an MS hotfix re. Microsoft Agent.

Ideas appreciated, thanks,

Martin
