--- Comment #2 from TomaszD dominikowski@gmail.com 2008-04-15 06:42:19 --- I still experienced the error after installing net11. So I installed net20 as well and the installation procedure has gone forward!
It's actually near the end of installation, during registering VBA product information, where WINE suddenly fails.
I'll attach the log in a moment. This is reproducible: always.
