can someone help me with creo 1.0 installation?

hello everyone, i have been traying to install creo 1.0 but something happens with the ptc page, when i choose the option: download creo 1.0 appears

different options to dowload but all of them are from creo 2.0, i have a license code from my collage but it is for creo 1.0 so the code that is send to my email is for creo 2.0 and i need it for creo 1.0. but as you see the page doesn't provide me any creo 1.0 download. I would really appreciate if someone could help me with this install process cause i have been traying a lot and nothing seems to work. thanks!
