Issues while installing PostgreSQL in Windows 10

When I tried to install PostgreSQL on Windows 10 (64-bit), I was getting a prompt saying:

'Failed to load SQL modules into the database cluster'

and

'problem running post-install setup'.

Did you install postgresql with administrator-privileges?

This might be due to a privilege-issue, you can try to:

Create a new user account, called postgres
Add the new account to the Administrators and Power Users groups
Restart the computer
Run a command prompt as the postgres user, using the command:runas /user:postgres cmd.exe
Run the installer from the postgres command window
Delete the postgres user account, as well as the user directory

Another option is to:

Uninstall PostgreSQL
Delete the postgres user if it still exists.
```
net user postgres /delete
```
Create the postgres user with a password
```
net user /add postgres <password>
```
Add the postgres user to the Administrators group
```
net localgroup administrators postgres /add
```

Add the postgres user to the Power Users group

net localgroup "power users" postgres /add

Run a command window as the postgres user
```
runas /user:postgres cmd.exe
```
Run the install file from within the command window.
```
C:\Download\postgresql-9.6.12-windows.exe // or whatever version you are using
```
This should run the installation successfully.
Remove the postgres user from the Administrators group.
```
net localgroup administrators postgres /delete
```
