Maybe he has anti virus/malware protection that prohibits - as they should.
As I don’t want any of that anti-software doing more harm than threats themselves - I am concerned of known threats at least.
I’ve tested the 7 most used anti stuff - and they make my machine run like a 90’s pc.
Every process open a bunch of dll’s it never was designed for or expected.
And turned off most stuff in realtime even - still recognize longer startup and overall slower everything.
So no anti-virus = you have to be careful about known threats
And I had close to no problems with any audio or video software for 7 years on my windows 7 i7-computer.
