Starting with Stylus Studio X15 Release 2 is possible to transfer a license from one computer to another without contacting our support team. 

When you activate Stylus Studio we build a unique hardware identifier and passed to our license server, this is helpful for tracking software usage with large organizations which may run hundreds of Stylus Studio instances. If you work on multiple workstations and try to activate your Stylus Studio license on a different hardware you get stuck on the following error:

This is no longer the case, just run the Stylus Studio un-installer ( Control Panel ->  Unistall Programs) and you are free to re-install on a different system.

There are actually two additional methods for deactivating a license: 

• From inside the IDE, click on Help -> Deactivate From this Computer.  This command is disabled in evaluation mode.
