INSTALLDIR's permissions seems not right. Directory permissions after install swift-5.7-DEVELOPMENT-SNAPSHOT-2022-06-04-a-windows10.exe on Windows 10 x64: ```powershell >accesschk.exe -d c:/library Accesschk v6.12 - Reports effective permissions for securable objects Copyright (C) 2006-2017 Mark Russinovich Sysinternals - www.sysinternals.com c:\Library RW BUILTIN\Administrators RW NT AUTHORITY\SYSTEM R BUILTIN\Users RW NT AUTHORITY\Authenticated Users ``` I don't think you want Authenticated Users Group has the write permission.
