When attempting to unzip a Power Point presentation Win Zip produces the following error:

"Error "Location Path": missing 3 bytes in Zip File - attempting to process anyway"

Windows XP Professional SP3
Win Zip 8.1 this is what we're licensed for
Microsoft Office Professional 2003

Steps taken so far:

Tried uninstalling and reinstalling WinZip
Tried repairing Office
I can open this on my computer without an issue

This generally means file corruption. You can try downloading WINRAR and seeing if it can make it past or repair the archive. If not, need to find the original copy of powerpoint and rezip it.
