How to open MW4 file?

An often recurring problem with MechWarrior Game Structure Format Archive is that MW4 is not associated with the correct program file. Thus, when you open MW4, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the MW4 file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install MechWarrior

In this case, you should first verify that the MechWarrior application is installed on the computer. This can be achieved by typing MechWarrior into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open MW4 files.

Programs to open MW4 file

Remember to download programs supporting MW4 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of MechWarrior with MW4 files

If, despite the installed application, the MW4 file does not start in the MechWarrior application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the MW4 file with the MechWarrior application.

Step 3. Update MechWarrior to the latest version

If, despite the association of the MechWarrior program with the MechWarrior Game Structure Format Archive file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Activision page and install.

Step 4. Check for the following problems with the MW4 file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The affected file may be 0 KB or smaller than expected. Usually this applies to MW4 files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the MW4 file that we want to open. As a result of the scan, sometimes it is not possible to recover MW4 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of MW4 file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged MW4 files. The easiest way to restore the file is from a backup or by contacting Activision, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted MW4 files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. Copying the MW4 file to another location will fix the problem.
This problem usually affects more complex files. In this case, the MW4 file is blocked by the first application to open it. Closing other programs should help. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the MW4 file for a certain period of time. If nothing helps, please reset the device.
