Hi - I have been trying without success to install 'fax services' in XP sp3 via Add/Remove Programs (Windows Components). First I found that I had installed the wrong version of sp3 so I installed the correct version over the top. The problem is that the 'fsx...dll files will not copy with no clue as to why. They all have an April date. Any ideas? TKIA edit: I get the following: "Setup could not copy one or more files. The specific error code is 0x4b8. Press OK to continue or Cancel to stop set up and try again. If you continue the components may not function properly"
