I had to fix this on a clients PC the other day where they had decided that Adobe Reader might be a better program to open ZIP files rather than the built-in capability of Windows (or any other decompressing utility for that matter).
This is how I fixed it.
First, check in Folder Option that the ZIP file extention is associated with Windows Compressed Files or something similar. If you are using programs like WinZIP or WinRAR. Reinstalling or reassociating the program should be enough…
However, if you are using the built-in Windows function, I also had to do this:
From Start > Run … type and run the following:
regsvr32 zipfldr.dll
Once you get the prompt telling you that it is registered, you should now been able to open ZIP files in Windows Explorer.

I have seen a lot of tools for work with zip files. But one of them saved me – fix corrupt zip once. It restored many my corrupted zip archives within short time and without even trying. Besides I recommended it some of my friends.
Interesting. I spose if you want to fix this with a tool, no worries. But I find this fix better as there is no extra software required.
