Hi, I have searched this group and have found where others have reported issues with initdb. A couple of our Windows XP SP2 customers are having problems upgrading to our latest release which includes version 8.2.4 of PostgreSQL. They are logged on as a local Windows admin. We use the MSI with silent install, installing as a service and creating a service account. The main problem we are seeing is that initdb fails during the silent install with a permissions error. There is no log for initdb in the tmp directory. I have read the PostgreSQL Windows Installer FAQ page that informs that the directories leading up to the install directory must have read access for the service account. I am not a Windows security expert by any means, so I am a little out of my realm here. My understanding is the initdb process is run as the service account that was just created. Since this account is created by the installer, what privileges will it be given? Does it inherit the privileges from a particular group? I have tried setting read access for Everyone on the parent directory, ie: C:\. Should I be setting some other group's privilege also? One of our customers cannot get the install to work on the designated machine, but can install on another machine that is supposedly set up identically. Obviously, there is some difference in the security settings somewhere. Thanks for any help, Brent ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org/
