Console error message 'No such object'

I've used Norton 360 protection for years so I stick with it but some of the newer features are a real pain. These days, Norton checks so many things whilst packages are downloading, installing and executing and unless you have every level of reporting turned on, all sorts of thing can happen without me even realising. I've had packages fail to install or have their contents silently removed as soon as they are installed and even my own standalone app, that does nothing more serious than processing MIDI and OSC data, flags up warnings until I add it to the exclusions list! And even if what I am dealing with is perfectly safe, Norton will flag it as an unknown and potentially serious threat just because it's not been added to their database before. That goes for Max, VST installations, and all maner of specialist stuff.

Windows Defender is even worse!

So, my bet is that whatever virus protection software you are using is deleting the files as soon as they are unpacked and saved to disk!

Robust virus protection is great for "normal" use and absolutely necessary these days but unless you are dealing with things that large numbers of people around the world are using every day, it can be a real pain in the ****!
