Recently I tried to install Sol on my sister's compute because she has Baldur's Gate now. So when I did it, I had practically no problem except for one:
Skipping [improved Irenicus (recommended, optional)]
Error: problem parsing TP file [SETUP-SOLAUFEIN.TP2]: Sys_error ("WeiDU.log: Permission denied")
ERROR: Sys_error ("WeiDU.log: Permission denied")
Also, now that I play the game, every single improved encounter besides Dragons and other such stuff seem to now exist, even though I haven't installed them.
I got the Torgal encounter, and the Kangaxx encounter, and various other stuff.
I don't know what's up. I did have to put the zip file for Sol on a CD and transfer to her computer that way if that's what's wrong.
