I have tried running it as an administrator, I have installed Microsoft Visual C 2017 Redistributable, and uninstalled and reinstalled serval times and cleaned up my computer, I have also tried to install in a different folder besides Program Folder and nothing is working.

PostgreSQL was developed for UNIX-like platforms, however, it was designed to be portable. It means that PostgreSQL can also run on other platforms such as macOS, Solaris, and Windows.

Since version 8.0, PostgreSQL offers an installer for Windows systems that makes the installation process easier and faster. For development purposes, we will install PostgreSQL version 12 on Windows 10.

There are three steps to complete the PostgreSQL installation:

Download PostgreSQL installer for Windows
Install PostgreSQL
Verify the installation

1) Download PostgreSQL Installer for Windows

Step 4. Select software components to install:

1. Downloading the PostgreSQL Package

To install PostgreSQL on your computer, you can download it from the official site or by using the download link for Windows. Once you’re on the right page, click the “Download the installer” link.

That’ll take you to the following page:

Click the installer that pops up in the bottom-left of your browser (you’ll see it there if you’re using Chrome—if not, double-click the installer from your Downloads folder).

2. Installing and Configuring PostgreSQL

To show you how to install PostgreSQL on Windows 10, I’ll have to explain the configuration process involved in the installation. It’s a configuration of some important parameters like the port number, your postgres admin password, and more. Don’t worry if you don’t know what any of these things mean! The installation is straightforward.

To start, click Next in the following window.

Choose the directory where you want to install PostgreSQL. It’s recommended that you leave the default as it is. When you’re done, click Next.

The next page shows the components that are going to be installed. Leave these options checked as they are, and click Next again.

Leave the data directory as the default, and click Next.

To install PostgreSQL, you need to choose a password for postgres superuser (administrator) permissions. This password will be used when you connect as the user “postgres” from the SQL client in the verification section at the end of this guide. Click Next when you’re done.

Then, you’ll need to choose the port number that the postgres server will listen to for requests. The default is 5432, but the installation wizard may suggest another if 5432 is already in use. Click Next to continue.

Now, you should see a summary of all parameters you set in the previous steps. Click Next again to move on.

On the following page, simply click Install.
