Unable to upload .doc files to any site, can anyone help me please?? - persists upload

I have MS Office. I tried to repair, install MS Office. I have also tried to format my system. But the problem persists. Everyone has the right solution for this? I use Dataone broadband and no problem with the ISP, how can I load a file. Doc on a computer to my friend who is with the same ISP.
