If you're using newer versions of Windows, you may have seen the following message when trying to install our (and many others') products:
It shows up on Windows 8 when using Internet Explorer, and on Windows 10 with any browser.
This is a part of Microsoft tightening security in fighting malware (which is a good thing!) but it does mean that many innocent executables will be blocked as well.
Long story short - if you get this message while installing our products, you many need to temporarily disable SmartScreen, or (a temporary workaround found to be working for now) running the setup from a network location (even the same machine, something like \\127.0.0.1\c$\temp).
Needless to say, our apps are completely safe, clean and do nothing more than enhancing your SQL Server experience.
Keep it safe! :)
