Cannot enter activation key


After having installed Nuitrack on my PC and used the license key successfully there, I wanted to install the program on my Laptop (MSI GE62 6QC Apache). However, the “Enter Activation Key” bar remains grey, meaning I cannot insert any key. Even after uninstalling and reinstalling multiple times, it doesn’t change.
I already found this thread Activating Nuitrack Pro and followed all the suggestions there, but it didn’t help.

Does anyone have an idea what else I could try or if there’s something I need to pay extra attention to when installing/uninstalling?

Best regards
