Archive Upload - Unzip failing to configure

I am struggling to get the unzip facility to configure for my gallery.

I have been given the path to the unzip bianry by my hosting company (/usr/bin/unzip) which i have entered but testing fails resulting in the error messge

"The path you entered doesn't contain a valid unzip binary"

I have also uploaded the correct version of Info-ZIP's UnZip into a folder called unzip in my gallery and tried pointing the path to that instead (file path is correct as text box browses the files) after having set the correct chmod permissions as instructed) but this also results in the same error message as above.

I'm at a bit of loss now. As the gallery is on a hosting company's server i am unable to make any changes to the server or php.ini etc as i don't have access, so i'm quite limited to what i can do.

I have seen many posts with this error but not one with a single solution to it so please could someone help

Cheers

Matt
