Cannot install "Fences3-sd-setup" on Windows 10

Clues please. Windows 10 and Malwarebytes.
This is the trial version. I am certainly willing to pay - but this is not a good start. I have looked at the Help messages but most seem to address folk who use Windows Defender as their prime protection. Google has a Malwarebytes incident listed within the last week.
Might this be my problem.
