Winclone does not allow to test Volume to Volume Cloning

[Former user]

I have updated PreBeta-Winclone_Build-48135_Version-9.0 to PreBeta-Winclone_Build-48137_Version-9.0 on macOS 11.0 Beta (20A5364e) Public Beta 3 Big Sur.

Winclone does not allow to test Volume to Volume Cloning, since when trying it says: License Key Required.

Should I use a special license for that? How?
