PostgreSQL version: 9.1.3
Operating system:   Windows XP sp3
Description:=20=20=20=20=20=20=20=20

I have run the postgresql-9.1.3-2-windows.exe at command window.
(postgresql-9.1.3-2-windows.exe --prefix "C:\PostgreSQL\9.1" --datadir=20
"C:\PostgreSQL\9.1\data" --mode unattended --serviceaccount postgres) When
installer's step came to the Initialising the database cluster, Did not
progress anymore.
I waited one hour. But installation did not complete.
Eventually, I canceled DB installer.

My OS version is Windows XP 32bit servicepack3

Best regards.
