Just tried to install a desktop publishing program called Spring Publisher. It has been around for a long time and gets decent reviews. I downloaded the file from CNET, so I think it's valid.
But I can't install it. It's an .msi file. It starts to run, I go through agreeing the the EULA, I get the pop-up asking if I really and truly want to allow this software to install itself on my system, I tell it to proceed -- and I get a pop-up telling me that installation of this program has been blocked by an administrator, contact an administrator for more information.
This is my personal Windows 10 computer. I am the only administrator, and I'm quite certain I haven't told my computer not to allow installation of Spring Publisher.
What's going on? I have never encountered this particular error message before.
