WL7-Licensing-Error-on-startup-but-I-have-a-subscription

In your case this message means that WL7 has been installed and run on too many computers in different countries simultaneously using one subscription. You can keep working with WL7 on the PCs where it ran before. However, WL7 cannot be launched on new devices until a brief cooling period ends. This is by design, no problem here.

only run 2 computers, and close all WL7

Error message to now.

Our licensing server shows successful activation and usage on more devices this month. You will have to wait until the cooling period is over.
