I did include this link in my post, describing my last installation attempt in detail: http://www.nma-fallout.com/forum/viewtopic.php?p=812117#812117 That did not work out very well. Maybe it was something wrong with one of my discs (tried the older one of my discs this time), but I certainly followed recommended procedure regarding RP. I now have a working game, and noted one (1) persistent bug with the multiple subsequent encounters on world map while traveling by car. This bug have occurred in both of my two recent installations, the one that was done by the book (but did not work) and the one I tried when the recommended way didn't work (which does work a lot better, for reasons currently unknown). I am sorry for not being able to determine what went wrong when I followed the recommended procedure.
