In fact, I can safely bet that no computer in the world can run all software out there, even if the software itself is ancient. And I'm sure if your computer can't run Tera, even well within the recommended specs, there's a lot of other stuff you haven't even seen out there your computer can't run as well.

Then why is it running on my computer? Or the next guy's computer? Why there's tons of people in Highwatch showing their red winged weapons and elin pantsu? What makes a game run on one PC doesn't necessarily make another game run.

'But I can run everything else BUT Tera, it must be the game. Thing is that computers are so similar yet so darned different, and even the slightest thing that nobody could suspect may prevent them from playing a game. The launcher and game seems to work for most people. It might seem like that if you check the forums, because everyone with a problem ends up here, but there's tons more people in game that never have problems and never complain.) (Aside, there's no way that 1/3 people have errors. PC hardware and software is too diverse to account for all the myriad ways a simple process can be screwed up. Where I think the launcher can improve most is to give more helpful error messages and to provide better information to help people diagnose their own problems. (I know because I've tried to help people solve hundreds of TERA launcher problems over the years.) any and all these things (and more!) can cause the errors you listed. Permission errors, connection problems, corrupt files, people trying to install mods and failing miserably, anti-virus/anti-spyware detection gone wrong, conflicts with other running software, problems with drivers, general hardware problems. even if you have the best launcher in the world, almost all of these problems are actually caused by issues on local computers.
