Is that an error from Steam? Have you checked the obvious things, like checking Steam has write access to the location you are trying to install / update to? Also, make sure there is enough available disk space at the target location.
If you’re able to run the game, but it’s crashing, make sure all your drivers are up to date (especially graphics card). Failing that, if you could follow the instructions in this thread to post up your log files, the devs may be able to help further to get to the route of the problem…
