Postgres install doesn't work on windows 7

[garegerret]

I tried to install HM 1 on windows 7 and it doesn't install postgres properly.
Setup was not completed succesfully and I get the following text:

What are your antivirus and firewall? Are you using user access control? Did you install the file running as administrator?
