It seems that the 30 days license is tied to a specific mac address. What about the paid license, is it tight to a specific machine? Do I need to get the vendor in the loop when installing on other machines?
The paid license is tied to a specific machine as well, but Rowley has no problems with sending you license keys for multiple machines, if you need them, even with the personal license. I have CrossWorks installed on my main development machine in my lab, the laptop I use on-the-go, and on the PC in my home office, all with keys sent by Rowley.
