Hi,

This is a duplicate of BUG #16341.

We have generated a "test" installer with the fix for v11 and uploaded it here<https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdrive.google.com%2Ffile%2Fd%2F1XTQo9C3ZEwQ7KuwOXmwBhC3FE77-chAP%2Fview&data=02%7C01%7C%7C53a3af4acd514412f21a08d7e50ad25a%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637229706954243674&sdata=rk3MogVB52rSiYIff2DgV9aPwekt0liQ%2BdLJ0Wi%2Fczg%3D&reserved=0>. Could you please verify if it fixes the issue? If it does, then we would release an update for all affected versions. Thank you.

PostgreSQL version: 12.2
Operating system: Windows 10
Description:

ICACLS error when installing under system context "NT AUTHORITY\SYSTEM" ie
installing with SCCM

System context has no user profile, the installer tries to set security
permissions to domain\hostname
The first call to icacls removes inheritance
C:\WINDOWS\System32\icacls "C:\Windows\Temp/postgresql_installer_9283e94fc0"
/inheritance:r

The next call adds permissions for domain\hostname$ (this should be "NT
AUTHORITY\SYSTEM" or "hostname\Administrators")
Executing C:\WINDOWS\System32\icacls
"C:\Windows\Temp/postgresql_installer_9283e94fc0" /T /Q /grant
"COR\Txxx6767$:(OI)(CI)F"

At that point the permissions on the folder have changed but the installer
no longer has access to the folder contents
So the next step fails
Error running C:\WINDOWS\System32\icacls
"C:\Windows\Temp/postgresql_installer_9283e94fc0" /T /Q /grant
"CORP\TM10336767$:(OI)(CI)F":
C:\Windows\Temp/postgresql_installer_9283e94fc0\*: Access is denied.

To reproduce the error use the Sysinternals tool
Open a cmd windows as admin the run
psexec.exe -s -i cmd
This will open a new CMD window in System context. install PostgreSQL

When installing as just and ADMIN user (with profile)
Executing icacls
"C:\Users\USER_adm\AppData\Local\Temp/postgresql_installer_57a6af5619"
/inheritance:r
the user is still the owner of the folder so can still make changes to it.

Note you are now adding the current user domain\user in the next call to
icacls.exe
Executing icacls
"C:\Users\USER_adm\AppData\Local\Temp/postgresql_installer_57a6af5619" /T /Q
/grant "COR\USER_adm:(OI)(CI)F"
So an Admin User install will work
But a System install will not.

I tried this will 12.2.2, 12.2.1, 10.12.2
