UnitySetup 3.5.6.exe the signature of this program is corrupt or invalid.

What does this mean when I download Unity? Is it because I have Windows 8?

Hello :slight_smile:

I had this exact problem, I couldn’t install any program on any browser, I also had installed Norton 360, turns out it was this as when I removed the software, everything functions normally and I just use windows smartscreen for security :slight_smile:

If you have any purchased security, remove it :slight_smile:
