That's what I'm asking you of, how did you replace it in a working system? I have reviewed the whole topic from the start but didn't notice anything like how-to. The dll can't be replaced neither on-the-fly nor in Safe Mode. Through the command line in RE - yes, it's possible.
OK but sad to hear.
I work under the limited account. That is, I can't elevate by just clicking 'Yes' in UAC prompt, I need to enter the user name and the password of an admin account.
