EVE Online - Patch Problems Explained @ Official Site

CCP makes a full disclosure about the reasons for the trouble caused for some Windows XP users by the recent Trinity patch.

It might appear from the installer log that we made the mistake of explicitly deleting \boot.ini instead of just boot.ini. The former would delete the file from the root of the current drive whereas the latter would only delete from the current working directory. It is not quite so; the mistake was to assume that the file would be deleted from the current working directory without giving the full path.
