Licensing - How do I re-install, rehost or transfer an Activation-based license


An Activation-based license is stored in Trusted Storage after being loaded on one machine.

It may be necessary to re-install or move the license from one machine to another for one of the following reasons:

  • The current machine is being retired.
  • The current computer has crashed.
  • Some major hardware devices on the current machine have been changed which can lead to machine ID mismatch.
  • The license administrator would like to move some licenses to another server.

How can the license be rehosted?


After activation, the license cannot be re-installed or modified. 

You will need to return the license to Xilinx from the machine on which the license is stored before you can generate a new license.

To return the license, see (Xilinx Answer 60525).

Note: In cases where the return operation is unavailable, you must contact Xilinx Customer Service to have the obsolete license removed from your account.
