I have a registered copy of Bliss v1.4 and I'm trying to install the latest version but every time I run either the 1.5.3 installer or the 1.5.4 installer I get the same message: Corrupt installation detected, check source media or re-download.
I've tried running the installer with the 1.4 version installed and not installed. I downloaded versions both from your website and download.com with the same result. Any help would be appreciated.
