Caulderone, thank you very much for having posted the information. Unfortunately, attempting to use the URL at the top of your post simply links to "This XML file does not appear to have any style information associated with it. The document tree is shown below." Following that is a huge page of code that has no download options.
I am running Windows 10 - after having used Windows XP for almost a decade - and have no idea how to locate Tequila (already downloaded) to run it independently, as there is no "Search" box or "My Computer" folder under which this sort of thing, I would expect, would be listed. Needless to state - and I know that it really does no good to inform the community at large about this, as there is not terribly much help that can be offered over and above what the hardware/software store has already done - but I am getting hugely frustrated and seriously p***ed off about how such a simple operation, which took the loading of two disks and an online registration to accomplish back in '04, is resulting in endless sisyphean "Sorry; can't do it," outcomes. If there is ANYONE who has experienced something like this situation, PLEASE advise as to what possible steps might be taken. I would really, really like to put this game on again, if only for weekend situations, and the apparently infinite list of locks on this, while others have seemed to have little to no problem, is something I would like to rectify as soon as humanly possible.
