Software Protection

We use CopyMinder® for our software protection.

If you have bought MechDesigner, you will have a Product Key, which you will need to install MD. Keep it safe, but PSMotion will be able to find it, as needed.

If you have a Network-License [sometimes called a Floating-License] then your I.T. department should do the installation and retain the Product Key.
