Failure when installing games "Error code: -11"

What is this error code -11?

First of all, you should always pay attention to downloaded file.. Most likely, it is not licensed, and therefore may contain a bunch of problems. Exactly "Pirate" games become faith in the impossibility of installing them. Extracting software from the downloaded archive comes into contact with many risks, because the probability of non-fulfillment of the operation is always preserved. The same rule applies to the load itself through the torrent.

Decision "Error -11 code" in games

First, analyze the game download process to your computer. Perhaps at some point the Internet connection occurred and the file did not fit or was broken by the integrity of the file. In another situation herself the game has already been broken (pirate version) or spoiled in the process of analyzing your antivirus..

  1. The solution to re-load the file, but before disconnect antivirus.
  2. Find an alternative this software. Pay attention to more early versions or other sources for downloading.

I think everything is simple. Exactly the downloaded file in 90% Cases is wine.

We try to unpack the archive

It is very recommended to all users on our PC several archivers. This is due to the fact that sometimes some specific archive is not amenable to open, because of what the user can receive a notice "Error unpacking unarc.dll". For such situations, it is better to try multiple archivers.

  1. Install at once two or three archivers with the best possible features: WinRar, Winzip., 7-Z..
  2. Alternately, try to open each of them.

Sometimes this method helps players in unpacking games.

These incomprehensible characters are caused "returned the error code: -11." Although modern developments have already been practically eradicated such a situation, but the user still falls on such cases.

  • Correct the name of the folder to which you are going to install the game. For example, if the folder is called GTA 5 online, then change GTA 5 Online.

In general, take a habit to always prescribe the names of the folders in English in the computer.
