License error in Creo 7.0 Student Edition installation

Hello everyone.

I have some troubles with the installation of Creo 7.0 Student edition. The first time I managed to download and use the software (from https://www.ptc.com/en/academic-program/academic-products/free-software/) I got the 7.0.1.0 version but now I find 7.0.0.0 as latest version (I suppose for the bug found in the former). Then I tried to migrate the software into an external hard drive and it stopped working (if I remember correctly I got error 0x00000003). I then uninstalled all the applications and deleted the licenses .dat files.

I try to reinstall the software and when I enter the simple license code (BK700908EDSTUDENTEDUNI) the installer program does not respond for some instants and then it shows an error under the license field.

How can I solve this problem?

I run setup.exe as admininstrator, accept contract and insert license codeAfter entering username and password and clicking "Install licenses"And finally I get this.
