I am not part of the TechTracker team and have not seen that limitation officially posted, but I would suspect the issue lies in the fact that the application itself never asks for your username/password. Thus, the only way it can identify you is by IP address, which assumes only 1 computer per IP address. If you have multiple computers behind a router, running TechTracker on one would 'overwrite' the results of the other.
However, that does not prevent you from running TechTracker on one computer, logging in, viewing the results, and then repeating on another computer. Provided you don't scan multiple computers behind the same router at the same time, you can therefore use TechTracker on as many networked PCs as you like.
Hope this helps,
John
I believe that I saw a posting that indicated you could only run TechTracker on one (1) PC per network. Is that correct? Where does it say that on the download website? Will wait for a response before I comment on this issue....
Thanks
