I've been using WinZip 11.1 successfully for ages, and yesterday, downloaded the free update to 11.2. Since then, I get this error message:-
"required file winzip.chm was not found in same folder as WinZip"and I can't use WinZip now....
Grateful for any advice.

i did a quick google search on winzip.chm
you can download that specific file from here: http://dodownload.filefront.com/7460685//e28de517cb0570418d5b6e26658aba0fb54667e0999a67e0802bf180809fe1c7c1855d56ccb 5ea69

If you cut and paste that file into your C:/program files/winzip directory it should work.
If not, i'd recommend reinstalling the whole thing.
