Avast Ransomeware Shield Not Installed, but still blocking software installs.

Avast Free Antivirus / Premium Security

Trying to update On1 PhotoRaw, and Avast kills the install every time with the error in the attached screenshot. “Allowing” the app doesn’t help - the installer can’t recover from the interruption.

Any thoughts? TIA!
