It says that personal license I bought lets me install DT Lite on 3 machines. But when I install it on my second PC it doesn't activate. Why is that and who do I contact to get my money back or fix the problem?
DAEMON Tools Lite provides its customers the possibility of contacting them through the Support form available on their website. All the issues with the registration and activation are handled by their support team.
