For the convenience of our users, we do allow for up to TWO simultaneous installs on separate computers as long as only one computer is in use at any one time. This means that you may install one copy of Reallusion programs and content on two separate computers without issue, but the EULA policy remains a “single-user license”, as in permanent use on more than one computer will require an additional license.

However you can always uninstall from one computer while connected to the internet and this will free up your license so you can install again on another computer.

I hope this helps explain the situation.
