http://www.cakewalk.com/register/faq.aspx Does this limit the number of times I can install my Cakewalk product? You can uninstall and re-install the software on your computer without having to worry about re-registering or being locked out of the software.
Per the End User License Agreement, your purchase of the software grants you the nonexclusive license to have one person use the software on one personal computer at a time. If you want to use the product on more than one personal computer at a time, or if you want to network the product, you must obtain separate licenses from Cakewalk.
If you have a second computer that you use on occasion, such as a personal laptop you use when away from your desktop, you may install the product on to the additional computer. You do not need to register the product again, simply use the same registration code tied to your account that has been generated for your unique serial number. Note that per the EULA, the software must only be running on one computer at a time unless you have purchased an additional license.
