Definitely need that Linux tag now.

First of all, I need to write down a pretty major apology, because I can't effectively use the search function on this forum at the moment. Due to a recent move I've been almost completely cut off from the Internet. I made I deal with our neighbour to leech a little on his wireless instead. The problem is that this connection is really, really, bad. I can barely connect at all. At times I get lucky and manage to send over small bursts of Internet, just enough to check my email or load a normal web page half-broken-ish. Loading many search pages and going through multiple threads simply takes hours at this rate. The bad (but better than no) Internet situation is going to continue for me until the 19th of this month, too long to wait. I just have to get to the bottom of this now, so I can play BG1Tutu ASAP.
Quick summary. I can't seem to install Tutu. I have successfully installed it on Linux in the past, but not in the last six years or so. I don't exactly remember what I did then, and things have likely changed a little in Wine if not Tutu itself.
Probably irrelevant technical data:
OS: Xubuntu 12.10
Wine version: 1.6-RC4
First attempt at running EasyTutu failed quickly. Running it from the file manager didn't do anything, it just briefly opened Wine and closes it again. I ran it through the terminal but I forgot to write down the feedback. Later I read somewhere that EasyTutu requires Dot Net to be present on the system, which I remember installing on Wine before, just not any time recently. I tried three versions of Dot Net, 3.5, 4.0 and something called Mono.
3,5 and 4.0 I just couldn't install, even though it gets a Gold rating on WineAppDB. The installation process just interrupts itself with a weird error displaying some half Chinese, half Windings garbage. Someone mentioned Dot Net requires the MSXML 6.0 PARSER to be present, so I installed that without a problem. Sadly it made no difference, the exact same interrupt kept happening.
So I switched to Mono instead, a relatively recent sort of replacement for Dot Net, written specifically for Wine applications. Installing Mono went without a hitch. Yet somehow this didn't fix my issues with EasyTutu. It acted the same as before, not really doing anything. So I ran it through the terminal again, this time remembering to copy paste the feedback I got from running EasyTutu. It may not hold any relevance, but here you have it all the same:

Does anyone have any ideas on what I could try next?
