CREO Parametric 6.0 Student edition installation

I am a college professor and have been teaching/using ProE/Creo for decades. I've installed and assisted students in installing CREO especially in the past 8 months. We use the install_creo6_unistudent_standard.pdf document.
Now I am trying to reinstall CREO 6.0 on my home PC again, follow these instructions, it seemed to work, the got a license failed. I did get a JRE not up to date, but no indication that CREO Parametric license failed.
I've wiped everything I can find that might be PTC related and tried again and now get the message above.
I would like to to load CREO 7.0 eventually, since some of my students have it and I can't open their files. However I can't find any CREO 7.0 student edition installation guide and I can't get past the Error!.
