emClient7 - setup.msi doesn't install

I have just downloaded setup.msi direct from the site, but neither double-clicking or right-clicking and selecting “Install” does anything… not even an error. I tried with the old setup.msi from version 6 and it still works fine. I am running on WinXP.

I may have a similar problem. My upgrade from v6 to v7 failed. As v7 attempted to launch I received an error window with the text below. I uninstalled v7 and reinstalled v6, and everything works again.

Oh, forgot to mention. I’m on Windows 10.

Okay, solved this myself… totally random. I right-clicked on the file and went to properties, and there was a message at the bottom saying that the file had been blocked from installing, because it was from an unknown source. There was a button to unblock. Good one MS, don’t give me an error when you don’t install, just do nothing and make me guess!
