Installation Problem Creo 1.0

Hi everybody !

It's now two days that i search all the way to find a solution to install Creo 1.0. I want to install the school version i'm following the process that the help gives you. The trouble is that when i'm downloading Creo 1.0 License utility i can't make it run my computer show me two possibility :

The installation is made correctly (if i press it nothings happen)

Make a reinstallation (if i press it well nothing happens too !)

I'm getting a bit crazy because then i can't create my PTC account and then i can't use it,

I need it for my school project so if you can give me some advice i would be grateful !

Have a good day and see you soon !
