You should have 'Logging On=1' in your baldur.ini file, which *usually* produces something in the baldur.err file. But not always.Nope, tried running that but there's no error report. Process starts, stops, that's all. I might try reinstalling I guess, unless anyone knows what's going on.Don't know, the BGMain.exe actually start the game, it should give you some kind of error report...Regrettably, after the install finished, I tried to run baldur.exe but it either CTD's instantly or the process just starts and quits without the window opening.
Your install, the way it is, probably *will* crash, but only after creating/importing a character and loading the starting area for BG2 (it would probably still work for BG1... for a while at least). This is because somehow BWS allowed you to install optional components of Infinity Animations without installing the main component (a bit of a WeiDU bug reported here). And I suspect the main component failed because you didn't have all the requirements (the setup-infinityanimations.DEBUG file should tell you).
But it sounds like you have other major issues if BGMain.exe doesn't even bring up the menu screen, let alone character creation etc. If you didn't install biffing, it could take a while to launch (several minutes sometimes) but it looks like you installed that too (which may also make uninstalling/reinstalling something like Infinity Animations difficult).
I went through some stuff but eventually gave up and have decided to do a new install, whilst removing a few mods. Is there any particular thing I can change to avoid the probable crashing you speak of? And how can I make sure I have all the requirements? I'm a bit of an idiot so I managed to avoid checking the error files you mentioned before deleting the entire folder :/
