Nope.Also, when it gets to 100%, just leave it be. It's a very long and agonizing progress ;-;
I think once I left it there for half an hour (Or longer) once and nothing happened. It's ran fine before, but I haven't played it for months and months.
nope
It took my comp like 2 hours :s
YepDo what I said. You won't have to re-download TF2, because that's kept somewhere else.
It took my computer 15 mintutes, and I can barely RUN TF2.2 hours is seriously bad.
