Natron Installer Won't Install

When I double-click on the installer, it won’t open the installer.
I’ve run the Windows install and uninstall troubleshooter.

Please download the Zip (no-installer) and try that.

For some reason Windows don’t like our installer anymore.

I’ll ask you a stupid question:
When I unzip the file, it just becomes a regular file. Is this supposed to happen? If so, then what should I do next?

i have never installed programs this way before.

You extract the ZIP, you then have a folder with the same name as the ZIP file, inside that folder you have a bin folder, from there you can launch Natron.exe.

ok thanks
