You may have to call License Management to request your license now. Try that first. Have your Service Contract Number available. You will find that in: Help --> About within Pro.
If you have the license file you should be able to switch the network card to a new machine as long as the software will run on the new machine.
Over the years, PTC's policy on this has changed.
One thing for sure: It won't be free.
Years ago, PTC would charge a $500 fee for each license server change.
Last year, we were considering to not renew our maintenace.
I specifically asked our rep if we could transfer licenses while off maintenance.
He said that PTC no longer offers this service, even for a fee.
He said we must be on maintenance to make such changes.
In Reply to georges bon:
We don't have maintenance anymore but we would like to receive licenses files.
I don't find how to on PTC web site but I'm pretty shure we could do this without maintenance in the pass.
Can someone tell me if it's possible or not please ?
Then, without maintenance, it's not possible to change its computer ?
