Thank you, Bernt. I downloaded both. The dotnet did not install, but only because it determined that it was already on my computer. Likewise, it wouldn't install c++ distro (vc_redist.x64.exe) for the same reason. I did install "vc_redist.x86.exe." I then rebooted the PC. However, when I opened Audiolense, I had the same experience. I was given the choice of what app I wanted to run. When I made my selection, the dialogue window closed and the app disappeared.
Any thoughts on what I should try next?
