Registration question

I have finished registration procedure, but when I open wavelab soft ware, it still Jump out of a window to ask me input activation code.
Dose anyone can help me solve this question?

You need to activate your Wavelab license in the the e-Licenser software that should be installed together with Wavelab. So open ‘e-Licenser Control Center’, click on ‘Enter Activation Code’ and add the license for Wavelab. This must be done with an active internet connection.

If you don’t have an e-Licenser you will need to purchase one from Amazon or your local supplier. FWIW

Unless it is Elements. Which, of course, the OP does not specify.
