Sorry but this is completely wrong information. There are way more than two reasons. It has nothing to do with being hacked.
Let me show you one really easy example. This an example of what happens to communication when things are run at two different privileges, not a “reason”.
Run your Cubase as admin. Now try and drag a wave file from your desktop into your project.
There may well be other applications that recommend running as admin. Cubase and Nuendo are not those.
Right that’s enough from me on this. I’m here to help, but certainly not to argue.
As mentioned earlier, if you want to run as admin this is indeed your choice.
Cheers, P.
