SubInACL is a command-line tool from the Windows Resource Kit that can be used to update file, folder and registry permissions, and can help fix some Access Denied errors that can be encountered while trying to install products, hotfixes and service packs on Windows. It enables administrators to obtain security information about files, registry keys, and services, and transfer this information from user to user, from local or global group to group, and from domain to domain. If you have it installed on your system, you will find its SubInAcl.exe file in the C:\Program Files\Windows Resource Kits\Tools folder. If you need to download it, you can do so here.
