Nuendo 7 and Cubase 9 Pro open Elements not Pro

Nuendo 7 and Cubase 9 Pro open WL9 Elements not Pro on a Mac here. I had Elements installed before Pro and moved the license to another computer. The Pro license allows to open Elements too. When I delete Elements nothing is opened anymore - I can’t switch to the Pro version. How can I fix this? Thanks.

I found the answer myself: the file “OpenInWaveLabElements9_0.aepp” has to be trashed. Now WL 9 Pro is opened by Cubase and Nuendo.
