Unable to open manager io

I have been using the desktop version for my records. However it has now stopped working. i have been using it not windows 10 but i has completely failed to run on it. whenever i attempt to run it the message i receive is that i find a version of my Pc from the software publisher. Could you please help me to resolve this issue. Anthony

Can you attach the image to show the entire message using windows snipping tool?

how do i get the software set up
