Freeware problems

Has anyone else noticed Windows 10 will not allow freeware to install any more?. I recently downloaded Free Cad with no problems but when I tried to install I now get a message that tells me to go to the Microsoft store and blocks the install. There are ways to get around this by editing the registry but I have found that simply going off line allows the installation and stops the Microsoft intercept. Hope this helps someone as I am getting fed up with being the victim of internet giants doing battle over market control.
