Zavesys If you truly believe you could play "several MMORPGs and recent multi platform titles
without ever needing those files", then, ironically, the reason you believe that is because the software you think you "never needed" is already installed and working as intended. My impression thus far is, frankly, that you have no idea what you are talking about. Your advice is based on flawed logic stemming from lack of understanding. My "no" was not about whether I was going to follow your advice, but rather that
nobody should follow it, because that is, simply put, bad practice.
Also, "your computer - your choice" should only apply to people understanding at least in part what they are dealing with. That is known as "being informed". And people looking for help are, by the very definition of their actions, unable to make an
informed choice. Like, for example, understanding why the copy of the game represented by your folder is presumably working just as fine as the copy I have:
P.S. Why are
you ignoring the fact that he/she uses an early alpha demo? It used an earlier version of MSVCR and the respective DLLs; the version linked in OP uses an updated one (and IIRC the demos after that - yet another).
