BUG #18572: Crash during postgresql-16.3-2-windows-x64.exe installation

The following bug has been logged on the website:

Bug reference:      18572

PostgreSQL version: 16.3
Operating system:   Windows 10
Description:

When installing on Windows 10 I've hit this error, displayed in a dialog
during unattended mode installation:

"Error copying file from packed archive [location] to [temp
folder]/prerun_checks.vbs: Destination not writable" with Abort, Retry,
Ignore

If I Abort, the follow up message is:

"system's temp folder is not writable by the current user"

The folder *is* writable by the user running the exe (who is a member of the
Administrators group, BTW). I've captured the
installbuilder_installer_[number].log file, but there's nothing very
obviously useful there (I've obfuscated my domain and user names):

As I recall, there was a similar issue in Windows Server for a time, fixed
in 16.3-2. There still seems to be a problem in the Win 1x OSes.
