Kathy from Logos has replied to my email in regards to running Libronix 3.0e under Windows 7,

Thank you for your email. Since Windows 7 is still a Beta, it is not compatible with Libronix because windows beta 7 has not yet been released. If our Libronix version if 4.0 is not ready when Windows 7 is released, we will update 3.0e to work on it.

From Phil Gon’s (one of the editors on the Logos Blog) website, he has successfully installed Logos on Windows 7 (x64); I will try to contact him and see if he can share some light on how to get the installer working.
