I just got my laptop back from repair and I'm trying to install PT4/PostgreSQL.

I Receive this message when installing postgresql...""Problem running post-install step. Installation may not complete correctly. the database cluster initalisation failed."

I done some looking around and found this solution which could possibly fix my problem...

Solution:
- Uninstall PostgreSQL
- net user postgres /delete
- Control Panel -> User Accounts -> Configure advanced user profile properties -> delete all "Unknown User" instances that seem to be left from postgres
- compmgmt.msc -> Local Users and Groups -> Users -> New User... -> User name: postgres, Password: postgrespass -> Create
- compmgmt.msc -> Local Users and Groups -> Users -> postgres -> Member of -> Add... -> Administrators -> OK
- copy postgresql-8.4.9-1-windows.exe to C:\
- runas /userostgres cmd.exe -> cd \ -> postgresql-8.4.9-1-windows.exe -> installed successfully without errors. Checked data folder and confirmed files created successfully.
- compmgmt.msc -> Local Users and Groups -> Users -> postgres -> Member of -> Administrators -> Remove
- compmgmt.msc -> Local Users and Groups -> Users -> postgres -> Member of -> Add... -> Power Users -> OK
- Installed HM2 -> created db successfully
- Restarted computer -> HM2 runs properly (i.e. just to check postgresql service starts automatically)

The only problem is, I'm totally lost at "- copy postgresql-8.4.9-1-windows.exe to C:\" and below, can anybody help dumb it down for me? Thanks.

copy the .exe installation file to C:\ folder?

How do I do that? What is the C:\ folder?

Windows-E -> Find (C : )
its the main folder

then you got to run CMD (command line), type: runas /user:postgres cmd.exe
cd \ - Goes to main C-folder.
postgresql-8.4.9-1-windows.exe - Type this and it will run the program.
Point here is to run the installation on different user.

I'm not sure getting into deleting potgresql specifics is the way to go. I had similar issue when hem2 partially installed after a format and re install of win 7.

Try and uninstall db, and/or remove registry entries for db/posgresql using an uninstall prog like ccleaner. Then re install.

I can't find local users and groups in compmgmt.msc....

I'm not really sure what I did but I deleted everything to do with postgresql, downloaded it manually (which I already tried to do) A window came up asking something about locale and I changed it from default to UK, now it works! Thanks for your help anyway guys!

Yeah, I had a same/similar PostGreSQL issue on one of my machines. Solution was to download it manually, separate from HEM.
