Description:

Hello, I've been trying so many things past few days, I've downloaded all
suported x64 install .exe's as well as x32 one's.
When I run the installer as an Admin ( i don't have any other user account
), I even tried to start the installer through cmd with admin privileges,
but everytime no matter what I do I get an error saying:

There has been an error.
Error running icacls
"C:\Users\Aaa\AppData\Local\Temp/postgresql_installer_34545234c" /T/Q /grant
"Aaa:(OI)(CI)F":
C:\Users\Aaa\AppData\Local\Temp/postgresql_installer_34545234c\*: Access is
denied.

I did not manage to find any information about this error it seems I'm the
only one getting it ( my coleages ) had no problem with it.
Thank you
