(Running Windows 7 here.) I've got a dll file that I need to replace, which gives read-only access to the administrator, so even as an administrator I can't change the permissions. It only gives full control to the TrustedInstaller account. What can I do to override these permissions?

Note that it is usually unwise to forcibly modify a system DLL. For one thing, it may get reverted unexpectedly at some point in the future. – Harry Johnston Nov 29 '11 at 1:21
It's not a system-critical DLL, it's only used by one piece of software (I know because when I uninstall the software, the dll disappears). – notfed Nov 30 '11 at 15:42
Thanks surfasb, I actually did this already, but was wondering if there's a way to do it without changing the owner of the file... – notfed Nov 30 '11 at 15:43

It might work if you use SYSTEM under your user rights. check my last post on how to do it. use caution when doing this. I highly advise that you know your command lines and how to use dos or some programing knowlege. this is not for the average user or admin for that matter.
