It sounds like either broken software, or software that's incompatible with our server, especially if 3 separate install attempts all led to the same bad result. Unfortunately we can't really assist with troubleshooting the actual software as none of us are familiar with it.
Have you asked on their forum about why you'd get this error when there's no prior installation and the system requirements are met? Specify when you start that you've already reinstalled 3 times and every installation had this error. It may be a bug they need to fix, or they may be able to tell you how to add the missing data.
