I bought the CS6 Collection and I have a youtube channel together with my cousin.
Can we both use PP with that one licence at both PC's at the same time? Or does he have to buy a own licence?
To answer your question, per Adobe's licensing terms you should be able to install most Adobe software on up to two computers, but cannot use the two computers at the same time.
Hope that helps!
Thanks, I need to be sure I'm giving out correct information as well.
