Hi @Kevin.C,
I believe the latest beta versions (3.22.14 onwards) of WaveForms are now signed as per this thread from last month:
The beta versions are freely available here:
The next release version of WaveForms will be signed as well, but I am not certain when the next release will be; it usually coincides with a compatible product release, but Digilent does not have anything to announce as of yet.
Let me know if you have any questions.
Thanks,
JColvin
