I'm trying to install PostgreSQL on a WindowsXP machine that once had a PostgreSQL 8.3 installation. As far as I could tell the original installation was removed, there is no PostgreSQL directory and nothing that looks like a Postgres file. However, when I try to do an install I get a popup with the message: An existing PostgreSQL installation has been found at C:\Program Files\PostgreSQL\8.3. This installation will be upgraded.
There is no such directory. PostgreSQL8.3 does not show up on the currently installed programs list. Do I need to do some sort of PostgreSQL specific uninstall?
