OK, I got to this forum through Google searching for my own problem, which in essence matches the original problem in this thread. I have since solved the problem, and wish to post the solution here for future Google searchers.
First, my problem: I wanted to do a repair install of Windows XP. So I did, and during set up, while it was copying over files, it said it couldn't copy licwmi.dl_. It was on the CD all fine and dandy, but it still wouldn't copy it over. Hitting cancel to skip that file, I went through 25 of them before giving up. I wrote them down, I might post the list here if I find that paper.
So, here's the solution: I did this based off of
http://support.microsoft.com/kb/818464. I rebooted off the Windows install CD, and hit R to go to the repair console. I then proceeded to delete c:\windows\security\edb.log. Then I rebooted the computer without going into the CD, and let the Windows installer continue (where in previous reboots it complained of not being able to copy files again). Once the installer loaded up, and before it could complain of not copying (which it would take about 5 minutes to get to), I hit Shift + F10. In the command prompt, I typed "esentutl /p c:\windows\security\database\secedit.sdb". And then I deleted c:\windows\security\edb0000
x.log. And this time, there was no complaint of inability to copy files. Yay!
