When i followed your procedure I also got 1.0.0.1. I know I have a newer version than you do. I also suspect the OS sets this value, hence I think it is not that reliable in comparing levels between us. Some things very specific about that version number make me question its usefulness. One, it has four number groups, not three. Second, the galciv release levels for the beta started with a 0, as in 0.52.016 (not a number I actually remember being used, but used to show the numbering pattern). Also, if you are using SDC (and you will be able to in a couple of days), the release levels shown by SDC are stored in the registry when it installs one of its products and extracted from the registry to show what level you have installed.
I have one other way of, perhaps, determining roughly what level of code you and fleshpile have. One of the properties of the file "calciv.exe" is its last modified date. It is not as reliable, since I don't have a chart that gives a correspondence of date to release level, but it will help.
