No. The single user license is not locked to a computer. You can easily "re-activate" your single user license on any computer.
Note: We use the same licensing technology employed by major software vendors like: SolidWorks, Adobe.
Note: Most of our competitors are very unfriendly to single users like you, and require the software to be locked onto one computer or they make you pay extra for a "dongle" that you have to carry around.
If having license freedom is important to you, then we are your solution.
