PostgreSQL version: 9.3.2
Operating system:   windows 7 ultimate
Description:

When I try to install postgres, at the end, I get the error: "Database
Cluster Initialisation Failed".
There is NO WAY to install this program, in win7.
I tried the versions 9.3.2 64 bits and 9.1.11 64 and 32 bits.

I just don't understand why EVERY software can be installed in windows,
includin wampp, and postgres has such a folder permission problem.
This is ridiculous and absurd, specially when you see that several versions
have the same behaviour and this is so many times seen in google's search.

It's a shame because it is a good product, at leas in Linux.
