I had both DbVis 11 and the 12 Beta installed (on MacOS 10.14.6) for testing purposes. I went to install the new 12.0 software today and it asked me if I wanted to update the existing installation. I assumed it would update the version 12 Beta but it overwrote my version 11 install. Argh!
Please give some indication in the installer of which existing installation is going to be overwritten. Some of us may have more than one installed.
Sorry for that.
I will add an improvement request for this.
