Hello ! I obtain an error message when I launch the upgrade.bat on windows 2000 server using an administrator account (the one used to install postgresql 8.3.0): insufficient privileges to install a system service. I log in with VNC, and I have the same message using Terminal server. Is this a problem with the installer or with my configuration ? What could I do or check to avoid this message ? I did not have this problem on my development server which is identically configured (appart the fact I do not use a distant connection) Thanks
