I'm trying to install latest version of PostgreSQL and the install keeps running into the problem of

Error running the Post-Install Step. Installation may not complete correctly. The data cluster initialization has failed.

I looked online and found a lot of solutions to the problem and I've tried most of them. However, I keep getting the same error, so I looked at the Install-Log and it say that Icacls doesn't exist, which seems new.

Called IsVistaOrNewer()...

'winmgmts' object initialized...



Ensuring we can write to the data directory (using icacls) to CORPORATE\pjy002:

Executing batch file 'radC235D.bat'...

'icacls' is not recognized as an internal or external command, operable program or batch file.

Some other important things.

  • Downloading PostgreSQL on a virtual machine

  • Am an administrator of said virtual machine or at least can get adminrights

  • Using Windows 10

  • Installing PostgresSQL 10.4

  • It looks as if you are running the installer as a domain user - try to run it with a local administrator account of that machine (not a domain account). I assume you are talking about the EnterpriseDB installer? You might want to try the installer from 2ndQuandrang maybe that works better with a domain account.

  • You can also try a manual installation using the ZIP binaries: See here stackoverflow.com/a/4974170 or here: stackoverflow.com/a/4256125

  • Cool, I'll try those things and see if they work.

  • I've tried the things you're talking about (except running it with an administrator account - need to get approval for that). 2ndquandrang seems to be getting close but I can't open up the application. I've tried the Manual installation but I keep getting the same error message.

  • Nowhere in the "manual installation" are you required to run icacls (which is a standard Windows command line tool - I am very surprised that it's not available on your computer)

Figure out the problem. Had to get elevated rights and then install it. Thanks to everyone that helped.
