Tetrad Installation problems, both on Windows and Linux CentOs

[valsasi...@gmail.com]

Dear all,

 

I am trying to install the latest version of Tetrad both on Linux (Centos Redhat) and Windows, but I get installation errors in both operating systems (see attachments).

 

- For Linux, I obtain following error:

 

Exception in thread "main" java.long.UnsupportedClassVersionError: edu/cmu/tetradapp/Tetrad: Unsupported major.minor version 52.0

 

- For Windows, I obtain following error:

 

"Failed to validate certificate. The application will not be executed"

 

How can I solve these problems? Any suggestion is welcome

Kind regards

Paola
