Hello Rubens, Do you have a valid PTC Account and Password? You can move the license in Pro/E using the Licensing functionality. Go to the http://www.ptc.com/support/index.htm link In this click the Licensing tab and then click the option "Reconfigure Software Licenses" You will then be asked through a series of steps where you can then move your license from one host id to a new host id. You will then be mailed the new license file from PTC which can be used to install Pro/E on the new machine. If you have any queries mail me on bronson.dmello@pdsol.com.au
