Need to move your license to a new machine? Here's how.
- Go to the iShowU Instant menu, and choose "Deactivate license".
- Select "Yes" in the dialog that comes next.
- Quit iShowU Instant.
The license has been returned to your "pool of licenses" (you can activate iShowU Instant on four (4) machines for personal use. Commercial users are required to have a license for each machine).
