Unable to open a file

Solved
Hello, for some time now, I can't open a file on the internet that gives results from a laboratory analysis. What should I do? It says "sorry, unable to open this file," I don't understand because I have always been able to open them. Could it be something to do with Windows 10? Thank you for your help.

  1. I believe I understand that this is an ActiveX control, and when I activate it, it refuses me, saying it’s from an unknown publisher, but there is no risk, it’s a laboratory. I’m a bit lost as I am not a pro on the net, thank you, best regards.
