Error Message:
Error! Could not find a Joomla! XML setup file in the package.
I checked, and it's there and it does not look corrupted.
Looks like you have two different zip files, one for the extension title link and another for the download button link. The one I had problems with was the button, so I tried the title link and it works. You might might to fix this as it's confusing without any obvious explanation.
