I tried to install FM (the one you have to download) onto a new server and just could not get it to install using Postgres. It seemed to have a problem with not finding the user and/or issues with virus scanners which were not running. All I can say is that the documention needs to be a lot clearer about usernames and what they expect to achieve. After hours and hours, I finally gave up and put Oracle 10g Express on and used that as part of the install. It went on with no problems at all.
Has anyone actually put on FM when using Postgres and it worked?
