Hi

Assuming you have the disc version - uninstall from the first computer and install on the second.

If you have the download version then first check that the download is still available - on the second computer go to the Migix website and click My Account top right of the home page

Login with the email address and password you used when you registered the software.

Click My Products on the left side of the next page - you should now see a list of your registered products and a download link if available.

Download and install. Uninstall from the first computer.

HTH

John
