Steam updates break off shortly before the end. What to do?

Yesterday I bought the game Tropico 5 on Steam. Everything should be completely installed and ready.

Only if I want to start the game he will make an update. He shows me that he starts the game after the update.
However, this never happens because shortly before the update breaks off again and again.
I also do not see anything, that game just does not start.

I have changed the download server, completely uninstalled Steam and pulled it down, emptied the download-chace. Everything without success.

I really do not know where the problem lies that he does not get the game insalliert.

I have an acer laptop.
acer Asphire 5750G

Enough memory free? The game also needs a lot after the download for the installation.

Yes, everything is fine

Would not that show me otherwise?
