My Vista wont install 0.29 or 0.30.

It installs elephant, but cannot install postgres.
The pop up window after finishing installing elephant is messed up (the labels showing in the popup are the programming labels in german where you cant understand what you need to type into..). By experimenting, it starts the installation of postgres but it fails, either because it says "elephant user already created" or it cant init the db, so it rolls back without installing it..

After like 20 tries I'm dissapointed :(

So I'm kindly asking for a step by step instalation (maybe with some jpgs too) so that we can all test elephant!
