When version 8.0.319.0 attempts to install, it goes through a couple of steps OK but then halts with an error message that it cannot find a file called NUP1734.msi
I have tried several times without success.
I am currently running version 8.0.312.0
The first 2 tries at installing were when I was on WIndows 7. I then upgraded to Windows 10 but I still get exactly the same result when I try to update Eset.
