Hello!
Installation went fine (doesn't work with wine), after installing MDAC 2.6 and JET (before, i got some error messages regarding "tresor"-functions).
Also online update works great.
The only thing left is online banking (not with hbci, but internet/web banking). I read that i need to install .Net framework to get it working (since it's some C#/.NET sub-application which handles the online banking in quicken 2006).
Installing .NET 1.1, I got 2 errors during the installation and online banking resulted in the same error.
Installing .NET 2.0 went fine without problems, but doesn't seem to be working since the online banking error didn't disappear.
Greetings and good work so far!
(I forgot: I used latest CrossoverLinux on Sabayon Linux(that's based on Gentoo))
