Question

I tried to install postgresql 8.4 in my windows 7 (64 bit). But it fails with following messages in log

Initialising the database cluster (this may take a few minutes)...
Executing cscript //NoLogo "C:\PostgreSQL\8.4/installer/server/initcluster.vbs" "postgres" "postgres" "****" "C:\PostgreSQL\8.4" "C:\PostgreSQL\data" 5432 "DEFAULT"
Script exit code: 1

Script output:
 CScript Error: Can't find script engine "VBScript" for script "C:\PostgreSQL\8.4\installer\server\initcluster.vbs".

Script stderr:
 Program ended with an error exit code

Error running cscript //NoLogo "C:\PostgreSQL\8.4/installer/server/initcluster.vbs" "postgres" "postgres" "****" "C:\PostgreSQL\8.4" "C:\PostgreSQL\data" 5432 "DEFAULT" : Program ended with an error exit code
Problem running post-install step. Installation may not complete correctly
 The database cluster initialisation failed.

I have googled about this and run the command ‘regsvr32 vbscript.dll’ and it shows the message ‘DllRegisterServer in vbscript.dll is succeeded’, but it haven’t solved my issue.

Also I set the default value for {B54F3741-5B07-11cf-A4B0-00AA004A55E8} in registry to the file path of vbscript.dll, but it also haven’t solved my issue.

How to fix this issue?

The article text:

I’ll keep this one short and sweet. For those of you that have tried
to install PostgreSQL (mine was 8.3.7-1) on Windows Vista and got the
error Database Cluster Initialisation Failed error at the end of the
install, read this.

The problem is that Vista has some safety features associated with
setting permissions on the Program Files folder. Basically, even if
you are an admin, you can’t change permissions on some folders like
Program Files and Windows folder itself. This causes initdb to be
unable to create some folders and the database cluster. What this
means for you is that you need to install PostgreSQL in another folder
that is not inside Program Files.

By the way, if you have forgotten your Postgres account password while
installing the first time, just open a Command Prompt in Vista (If you
don’t know how, Google for it). Then type the command “net user”. You
will see a list of users on your computer. Find Postgre’s account.
It’s usually “postgres“. Then you need to change its password by
typing “net user postgres new_password” where new_password is… well, a
new password for the account. You will be needing that postgres
account during install. You will need admin privileges to do this
change however.

Firstly, uninstall any failed installations. Use the Control Panel or
the PostgreSQL installer in the install folder.

During the install, you will be prompted to choose where you want to
install the program. Just select a location in another place. Like
“C:\PostgreSQL” or something similar. It may even be on your desktop.
But not inside Program Files. Not inside Windows folder. However, it’s
not as easy. Bear with me.

After the install, you will still see that darned error message (or
something like non-fatal error occured). Do not despair! (For Windows
Power Users, we are just assigning Full Control permission to Postgres
account on the new PostgreSQL install folder). For other users, read
on if you don’t know how to do it.

Go to where you just installed PostgreSQL. In this case, the C:
drive. There, right-click on the folder (usually called PostgreSQL),
and go to Properties – Security tab. Click on the Edit button. You
will now see some usernames and other stuff. Click on the Add button.
In the “Enter the object names to select” box, enter “postgres” and
press Check. Postgres’ user account should appear there. Click on Ok.

Now from the “Group or Usernames” box, select the Postgres account. In
the window below, with lots of checkboxes, assign permission “Full
Control” in the Allow Column to it. Note, if you don’t want to allow
full control, just give it read/write. But I just went ahead and gave
it Full Control. (I was tired and annoyed. The “World’s most advanced
open source database” had failed to install!). Click on Ok and wait a
bit for permissions to be applied.

Then, just do a re-install. Do not uninstall anything. Just run the
setup again. It’ll say that a PostgreSQL install folder already exists
and other stuff. Just click on Next until the install finishes. If you
see “file cannot be copied” errors, click on the “ignore” button when
needed.

That’s it. PostgreSQL should be up and running on Vista now. Hope it
works for you too as it did for me, and that my guide is helpful to
anybody. If it works, or if you have other solutions, let us know.
Thanks for reading! 🙂
