What is MEXW64 file?

The file with the extension MEXW64 is the Misc Files file type. In addition to this file, the Misc Files category includes 6033 related files. MATlab Compiled Function Format appears on 1 operating systems as a functional file. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. The main program that supports this format is MATLAB. This was created by MathWorks, Inc..

How to open MEXW64 file?

An often recurring problem with MATlab Compiled Function Format is that MEXW64 is not associated with the correct program file. Thus, when you open MEXW64, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the MEXW64 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 MATLAB

An often overlooked issue is to make sure that MATLAB is installed on the computer. This can be achieved by typing MATLAB 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 MEXW64 files.

Programs to open MEXW64 file

Remember to download programs supporting MEXW64 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of MATLAB with MEXW64 files

If the application is or has been freshly installed, but the MEXW64 file still does not use the MATLAB program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting 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. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the MATLAB application as the default for handling the MEXW64 file.

Step 3. Update MATLAB to the latest version

If, despite the association of the MATLAB program with the MATlab Compiled Function Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the MathWorks, Inc. website or update the program from the application.

Step 4. Check for the following problems with the MEXW64 file

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

The MEXW64 file may be unusually small compared to the original file. This is most often caused by a problem while downloading the MEXW64 file. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file MEXW64 or the program directory. As a result of the scan, sometimes it is not possible to recover MEXW64 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of MEXW64 file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular MEXW64 file corruption. You can restore the file from a backup or use help.
The program indicates that the file is encrypted or corrupted. The encrypted MEXW64 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. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the MEXW64 file to another location.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. However, some background programs may block the MEXW64 file while scanning. If this does not work either, restart the device.
