Operating system: Vista
Description: Error on database cluster
Details:

When installing postgreSQL i ran into an error when it was initialising the
database cluster.

Previously i had installed postgreSQL on my other pc on which it worked fine
however when i install it now i run into the following error:
"Faied to run initdb: 1!
Please see the logfile in 'C:\Program
Files\PostgreSQL\8.3\tmp\initdb.log'.
Note! You must read/copy this logfile before you click OK,
or it wil be automatically removed."

When i check the logfile it gives the following message (was in dutch so ill
try to translate it as good as possible):
The application couldn't be started cause the configuration next to
eachother aren't good. Read the Eventlog for more information.

The dutch text was:
De toepassing kan niet worden gestart omdat de configuratie naast elkaar
onjuist is. Raadpleeg het gebeurtenislogboek Toepassing voor meer
informatie.

Thanks for any help that can be send,
