Neither can I
I have the same problem too. For for the past 2 years, I've been getting that flaming message about so-and-so not being able to find its zoneoc.dll in the Setup Library whenever I try removing windows components with Disk Cleanup. The message also gives me the error message ID "0x7e," suggesting that I go talk to the system admin. Well... people just might think I'm crazy if I go around talking to myself

I've researched this for over an hour now without being able to figure out diddly squat. However, I have managed to find a replacement zoneoc.dll but still no clue which windows directory it belongs in. Anyone know? Thanks in advance!

p.s.- I also have a problem getting into my User Accounts in the Control Panel- Whenever the button is clicked, the hour glass cursor shows for a fraction of a second and that's it. In order to dodge this issue, I simply alter my account through "Administrative Tools." In the event I want to change my account icon, I simply go to the folder where the icons are kept, put a new photo in, and change its name to activate it. Since this is probably of no relevance to the first problem, I will also put it in a separate post.
p.p.s.- To Microsoft's OS programmers- PLEASE stop making nonsensical error messages! They're annoying and retarded.
