Why do you use an AV software on Windows 10, btw? Windows Defender is pretty much on-pair with any thirdparty software. 😀
But to turn it more serious, I just submitted the installer for whitelisting to McAffee. Clicking Restore should allow you to install it, so if it doesn’t, then that’s an issue on their end.
Apologies for the trouble. I’ll report back once the whitelisting is confirmed.
