Scapple Trial Installation Not Working [Win10]

I have bought scapple and was downloading the trial version, but whenever I click the installer .exe file I always get the “Would you like to allow this program to make changes to your computer?” popup. I click yes, the cursor goes to a loading cursor for a few seconds… and then it stops and the program never even tries to open/install. I’ve also tried running it as an admin but nothing has worked so far. I also tried restarting my computer, but this also didn’t work. Is there anything I can do?
