Problem running post install step postgresql windows 10

i got a new laptop from Dell(XPS 15), with Windows 10 Pro.
I have always the same issue During installation of postgres «Problem running post-install step. Installation may not complete correctly. The Database cluster initialisation failed.» .

i tried a lot of solutions of past threads:
Install postgres not into progam files
create a user named postgres with full access to postgress directory, explained here https://www.youtube.com/watch?v=pS_zWDDDSe0
Checked for new win-updates
Turned off Firewall and Antivirus of Windows.

Just had this issue with postgres 12 my method to solve it is similar to Atif’s but uses the command line:

1. Uninstall PostgreSQL

2. Delete the postgres user if it still exists :

   net user postgres /delete

3. Create the postgres user with a password you can remember:

   net user /add postgres [password]

4. Add the postgres user to the Administrators group:

   net localgroup administrators postgres /add

5. SKIP this as group no longer exists on win 10 and default users
   should have necessary permissions — Add the postgres user to the
   Power Users group

6. Run a command window as the postgres user: (opens up new command
   window) :

   runas /user:postgres cmd.exe

7. copy the install file to a location reachable by that user and run
   it e.g.:

   C:\Download\postgresql-12.4-1-windows-x64.exe

8. Remove the postgres user from the Administrators group:

   net localgroup administrators postgres /delete

That’s it.
Hope this is useful

Just little addition to the answer from Anton Kudryavtsev:
Check that there is no Autoran parameter in registry: \HKEY_CURRENT_USER\SOFTWARE\Microsoft\Command Processor

Its’ deletion solved the error The program "postgres" was found by "C:/Program Files/PostgreSQL/14/bin/initdb.exe" but was not the same version as initdb in my case
(checked in Windows 10 x64 and Postgress 14.5 .exe installer)

Uninstallation may not remove all registry entries. You may type registry in the taskbar search and open Registry Editor.

Navigate to:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE

And remove entries pertaining to postgresql.

Installing PostgreSQL on Windows with the EDB installer is begging to get bald(er) faster. You can run PostgreSQL on WSL (Windows Subsystem for Linux) and connect to it on Windows!

Open Windows Terminal/PowerShell as administrator (right click the start-icon on Windows 11 -> Windows Terminal (administrator). Type:

wsl --install

Reboot your computer. After login Ubuntu will automatically be installing, WSL2 and Ubuntu is standard on Windows 11 (check documentation on how to select a different distro, etc.) Follow the instructions to enter your desired username and password.

Update Ubuntu:

sudo apt update && sudo apt upgrade

Install PostgreSQL:

sudo apt install postgresql

Give the ‘postgres’ user a password:

sudo passwd postgres

Start the service and open psql shell:

sudo service postgresql start && sudo -u postgres psql

Notice that the password you created is not the DB password for postgres, so unless you create a new user you can give postgres one in the psql shell:

ALTER USER postgres PASSWORD 'mypw';

Now you can install pgAdmin or use your own program (in ‘normal’ Windows) to confirm that you can connect on 127.0.0.1 with port 5432 (may vary) with the user postgres and his password.

Same problem. Beta UTF-8 was not selected. However this gave me the idea.

I was trying to install using different locale than the default locale of the system I am using. Tried a couple of times.

Installed successfully using the default locale.

You can refer to my method
I deleted the pgadmin folder in C:\Users\nameuser\AppData\Roaming and deleted the folder C:\Program Files\PostgreSQL
Then I uninstalled postgres and reinstalled.

While installing PostgreSQL I keep getting the message:

«Problem running post-install step. Installation may not complete
correctly The database cluster initialisation failed.»

This seems to prevent me from using PGadmin correctly.

In the install log I have found the following section which seems to indicate where things went wrong.

I haven’t been able to find a solution to this problem.

Executing batch file 'rad7C33E.bat'...
    The program "postgres" was found by "C:/Program Files/PostgreSQL/11/bin/initdb.exe"
but was not the same version as initdb.
Check your installation.

I have tried the following without luck so far:

• https://www.2ndquadrant.com/en/blog/postgresql-cluster-initialisation-failures-no-error-windows/

and many more!

If anyone knows what could be the problem I’d be very grateful!
