Last thread is full, so here's a new one. Not too much more to say: Last thread is http://www.gamesas.com/bgsforums/index.php?showtopic=930710, download is http://sourceforge.net/project/showfiles.php?group_id=247976, there's some forums http://sourceforge.net/forum/?group_id=247976 if you have something to post that you don't think belongs in this thread. Changelog is http://timeslip.chorrol.com/fommchangelog.html, or http://fomm.svn.sourceforge.net/viewvc/fomm/trunk/?view=log for a bit more detail. Latest version at the time of posting is 0.9.2, .3 should be ready on Saturday, and will have better mono compatibility and a few bug fixes. If there was anything I've promised to do and forgot about, now would be a good time to remind me.
vista users should either disable UAC or install fallout somewhere outside the program files directory to make sure they can install mods correctly without them ending up in the virtual store. (Setting fomm to run as administrator on the compatibility tab will work too, but make sure you set fallout and its launcher, and every other fallout related utility you use too.)
And finally, a couple of useful snippits from the readme:
If fomm crashes on startup with a generic windows error then you likely have a problem with your .NET installation; fomm requires .NET 2.0 to run. Among the other third party gunk that the fallout 3 installer installs alongside the actual game is the original prepatched version of .NET 3.0, which under some circumstances can cause .NET 2 applications to break. In this case visiting windows update and installing the .NET 3 patch it offers you is sufficient to get fomm working.
