OK
I went to http://www.ptc.com/academic-program/products/free-software/creo-college-download where I filled the form.
After that I was sent to http://www.ptc.com/academic-program/products/free-software/creo-college-download/thank-you where I downloaded the installation instruction as a pdf.
I opended the pdf, opened the link www.ptc.com/appserver/auth/it/esd/academicFree.jsp ,
I created a student account to download the file in www.ptc.com/appserver/common/account/ptcacademic.jsp
I accepted the export agreement and downloanled Creo 3.0 version WIN 64 DVD
I disable the antivirus and firewall
I unzipped the file and executed setup-schools.exe as administrator
In the installation wizard I accepted the software license agreement and I checked the compliance box, then clicked next.
Then I get a window that says that I need to log in to PTC.com and after entering my information the program stops working.
Yes I have internet, and I also tried with Creo2.0 but I get the same error.
