The SDL Wordcount Copy installer does not work

Hi,

I've never had any trouble installing apps from OpenExchange, but SDL Wordcount Copy just does not work. The buttons are missing from the installer screens, please see below. When I press Enter in the first screen, it does take me to the second, but that trick does not work in the second screen, so how should I install the app?

Does anyone else have this problem? Do you have any suggestions?

Thank you,

Jolanda
