I am trying my hands on Project-open a free open source tool for projects, time-sheets and HR maintenance.
I installed Ver 3.5 in Windows XP Machine did something and forgot it. After some days when i tried to use it the administrative password entirely skipped my mind. So i uninstalled it and again when i tried installing i faced these two errors.
"Warning :PostgreSQL is already present in this computer ! The installer cannot continue"
"Warning: the user postgres is already present in this computer! The installer cannot continue!"
To Remove First error:
1) I used Control Panel-> Add remove program to remove project-open. I also used CCleaner to clean registry but the same error keeps coming. I used Revo uninstaller also but it showed no reference to PostgresSQL.
So i started searching registry -> Regedit-> search for "postgres" . I found four reference to postgres in windows registry.
1) "HKEY_LOCAL_MACHINE\SOFTWARE\PostgreSQL
2) HKEY_Users
3) Somewhere inside Windows
4) Somewhere in Current Version -> Profile List.
I deleted all and i got rid of first error but second started coming.
2) To Remove second error i searched Google and found that we need to remove user from
My computer-> Manage-> Local Users and groups->Users-> delete "postgres" user
Also thorugh command promt u can delete the user by giving following command in command promp:
net user postgres /delete
After this i was able to install Project-open again.
Its there in project-open documentation also :-) got when i solved the problem :-)
